Act 4

Act 4. Selling More Than One Candle

Where the profit actually lives: add-ons, discovery sets, gift bundles and the shipping bands that make a second unit feel free.

Section 01

Why average order value is where the profit lives

Fixed per-order costs (packaging, postage, card fees, listing time) do not scale with unit price. A second unit in the same shipment is disproportionately profitable.

Every order you fulfil has a floor of costs that does not care how many candles are in the box. Packaging, postage, the card processor's fixed component, the ten minutes it takes to pick, pack, print and photograph the parcel. Call it around $6.35 on a typical UK small-parcel order, roughly $8.89 on a US Priority Mail equivalent. Whether the box contains one candle or three, that $6.35 is spent.

That is why the second unit in the same shipment is where the profit actually lives. The wax and fragrance still cost what they cost, but the fixed costs are already paid. On a $30 single-candle order you might net $7.62 after everything. Add a $10 wax melt to the same box and you might net $14 on a $41 order. The unit price went up 33 percent. The take-home nearly doubled.

The worked example that changes how you price

Take your true cost of goods on your best-selling 200 g candle. Call it $7.62. Add packaging and postage of $6.35. Add the Etsy fee stack of about $5.08 on a $30 sale. Your net is $11. Now add a matching wax melt with a true cost of $1.52 and a price of $10. The fee stack rises by only about $1.65 because most of the fixed component is already paid. Your net on the bundle is around $19, on an order that took you the same fifteen minutes to fulfil as the single candle would have.

That is the AOV lever. The rest of this act is a list of the add-ons that actually work for candle makers, ranked by the demand a real shopper is bringing in the door.

The candle business that survives is the one that gets a second unit into the same shipment. Everything else is a variation on that trick.

Section 02

Wax melts, the single biggest add-on in the category

Same fragrance, same wax pot, no wick R&D, and the shopper is already searching for it. The highest-ROI add-on you can offer.

Wax melts is a high-volume search term in every keyword tool I have checked (Google Keyword Planner, Ahrefs and Semrush all place US monthly search volume in the low tens of thousands, comfortably higher than how to make candles). Whatever the exact number this month, the direction is clear: shoppers who want a flameless version of a scent they already like are searching, and if you do not offer one, that demand goes to a competitor.

The good news is a wax melt is almost free to add to your range. Same wax pot, same fragrance, no wick to test. The technical work is a one-day exercise and the SKU pays for itself inside a month.

Making a wax melt from your existing candle recipe

Melt your normal container wax to 80°C. Add fragrance at the same load percentage you use for the parent candle. Stir for two minutes. Pour into a clamshell mould at 65–70°C. Cool at room temperature for two hours. Pop out. Cure for a full week before you judge the throw.

The one adjustment: most makers push the fragrance load one percentage point higher on melts than on candles. Melts have no flame to burn off oil, so the top note stays longer and the throw is stronger per gram of wax. Do not go above 12 percent on soy or you will get seepage on the clamshell.

Pricing the melt against the parent candle

A 100 g clamshell of wax melts should retail at roughly 40 to 45 percent of your parent-candle RRP. If the 200 g candle sells at $30, the matching melt sells at $13. That ratio protects the candle from being cannibalised (the melt is not a cheap substitute, it is a flameless version) and it keeps the true-cost margin healthy because clamshell packaging is a fraction of the cost of glass.

Section 03

Discovery sets and gift boxes

Mini candles for shoppers who won't commit to a full-size scent yet, and two-candle gift boxes for the shopper who is buying for someone else.

Mini candles and candle gift set / candle gift sets are both mid-volume search terms in the major keyword tools (typically a few thousand US searches a month each, at the time of writing). Treat the exact numbers as a moving target and check your own tool of choice before betting a range on them. What matters is the shape: this is a real audience with two different jobs to be done, and both can be served from the same range of finished candles.

The three-tin discovery set

Three 60 g tins of your best-selling scents in a slim mailer. Priced at roughly 1.4 times a single full-size candle. The pitch is try before you commit. The shopper who buys a discovery set is a shopper who returns for the full-size of whichever scent they liked, which means the discovery set is really a customer acquisition tool that also happens to be profitable.

Assemble discovery sets from candles you were already pouring for retail. Do not create a fourth SKU per scent. Pour a batch of miniatures once a month using the tail end of your normal pour, and store them in a labelled bin until you have enough to build sets from.

The two-candle gift box

Two full-size candles from complementary scent families in a rigid mailer with tissue and a printed card. Priced at 1.85 times a single candle, which is a small explicit discount versus buying two separately, but with a per-order margin that is significantly higher because you paid postage and packing once.

Curate the pairs, do not let the customer pick freely. A gift set is chosen by someone who trusts your taste, not by someone who wants to build a bespoke box. Two curated pairs (one warm, one fresh, for example) will outsell twenty custom permutations and take a fraction of the fulfilment time.

Section 04

The care card as a free upsell surface

A printed insert costs pennies, ships free with every order, and is one of the few recommendation slots you fully own.

Every candle you ship should carry a printed care card. The safety copy is a legal habit worth having, but the back of the card is also one of the best recommendation slots you own. It arrives in a physical box, in the hand of a shopper who has just decided they trust you.

What actually goes on the card

Front: trim to 5 mm before every burn, first burn to the edge of the vessel, never leave unattended, never burn near curtains or pets. Six lines of safety, one QR code back to your website.

Back: three product recommendations, chosen by scent family, with a small photograph and a discount code that expires in 30 days. The code drives urgency and gives you attribution so you can measure whether the card is actually working. Track redemption over the first few months and treat that as your own private benchmark. A very low rate means the recommendations were wrong for the customer. A surprisingly high rate usually means the discount was more generous than it needed to be.

The three recommendations that convert

First slot: the wax melt version of the candle they just bought. Cross-sell on scent, not on category. Second slot: another candle in an adjacent scent family from the wheel in Act 3. Third slot: your refill or subscription option, if you offer one. Do not use the third slot for a random discount. Use it for the durable habit you want them to form.

Section 05

Bundle pricing without eroding the single-unit margin

The formula that lets a bundle look like a saving to the shopper while keeping more margin than two individual sales.

The wrong way to price a bundle is a flat percentage off. A 10 percent bundle discount trains buyers to wait for the discount and eats your margin on the units that would have sold anyway. The right way is to price the bundle at the sum of the units minus the fixed costs you actually save by shipping them together.

The formula

Bundle price = sum of unit RRPs minus (packaging saved plus postage saved plus card fee saved). On two candles in the same box: packaging saved is roughly $1.02 (one mailer, one tissue, one label). Postage saved is roughly $2.79 on a UK small parcel because a two-candle box still fits in the small-parcel band. Card fee saved is roughly $0.38 because the fixed component is charged once. Total saving passed on: $4.19. Two candles at $30 each become a bundle at $57, not $55 (10 percent off).

That $1.91 looks like a rounding error. It is not. On a hundred bundles a month it is $191 of margin the flat-discount approach would have given away.

Anchoring the saving so it feels generous

Display the bundle as sum of units struck through, bundle price beside it, then the saved amount in a small line underneath: Save $4.19. The number is honest, the maths is transparent, and the shopper sees a saving without you having to invent a promotional discount that comes out of your pocket.

A bundle is not a discount. A bundle is a rebate of the fixed costs the shopper let you skip.

Section 06

The two shipping tricks that make add-ons feel free

Free-shipping thresholds that lift AOV, and the packaging weight sweet spot that keeps a two-unit bundle inside a one-unit shipping band.

Two operational tricks do more for AOV than any pricing exercise. Both are boring. Both work every time.

Set the free-shipping threshold above your current AOV, not far above

If your average order value is $28, a free-shipping threshold in the $38 to $41 range is a common starting point. That is the kind of number that can nudge a single-candle shopper into adding a melt or a candle care accessory to qualify. Set it too close to AOV and you give away shipping on orders that would have hit the threshold anyway. Set it far above and shoppers see it as unreachable and give up. Somewhere around 1.3 to 1.5 times AOV is a sensible place to start, then A/B test it against your own data rather than trusting a single magic multiplier.

Keep the two-unit bundle inside the one-unit shipping band

This is the packaging trick nobody teaches you. UK Royal Mail small parcel tops out at 2 kg for the same rate as 100 g. USPS Priority Mail Small Flat Rate is fixed regardless of weight up to 70 lb. Australia Post has a 500 g band and a 3 kg band with a big price jump between them. If your one-candle box is well inside a band, a two-candle box will almost always ship at the same rate. If it does not, redesign the packaging until it does. A rigid mailer that is one centimetre shorter is worth the redesign hours.

Section 07

Refills and subscriptions, for makers with 20+ orders a month

When it makes sense, when it does not, and honest churn expectations before you commit to the operational overhead.

A refill programme (a candle poured into a vessel the customer already owns) turns a one-off sale into a repeat-purchase engine and cuts your per-unit COGS by the price of the glass. A subscription (a candle a month, or a discovery box a quarter) does the same thing on a schedule you can plan production against.

Neither is worth the operational overhead below roughly 20 orders a month. Refills need a return-and-refill logistics loop, subscriptions need a recurring-billing surface and a churn management habit. Under 20 orders a month you should be pouring, testing and improving. Above 20, the compounding return on retention starts to outweigh acquisition.

Honest churn numbers

Consumer-goods subscriptions with monthly billing are widely reported to churn in the region of 10 percent a month or more in the first year (see for example the Recurly and Zuora subscription benchmarks). Candle subscriptions tend to sit at the higher end of that range. Skip-a-shipment options, quarterly rather than monthly billing, and a genuinely surprising scent each month all pull churn down, but expect to lose a meaningful share of subscribers over the first six months and plan the economics around that, not around a best case.

Refills tend to churn less because the customer already owns the vessel and has a physical reminder on their shelf. I do not have public retention numbers I trust to quote here, but in my own shop, refills repeat more often than a fresh candle sale to the same customer. Measure it on your own orders before you build a forecast on it.

Section 08

The marketplace fee is a discount you can give the customer instead

Amazon, Etsy and eBay each take a fee on every sale. On the second purchase, that fee is a budget you can hand to the customer as a direct-site discount, if you do it inside the platform rules.

A repeat customer bought on Amazon Handmade or eBay costs you roughly 12 to 15 percent of every future order in referral fees (Amazon Handmade fees; eBay standard selling fees), forever. The same customer buying direct on your Shopify or WooCommerce shop costs you around 2.9 percent plus $0.38 in card processing (Stripe pricing). On a $30 candle that gap is $3.05 to $3.68 per unit, per reorder, for as long as they keep buying. Ignore it for a year and you have handed the marketplace a four-figure sum out of pure margin. This is the AOV argument from earlier in this act, applied to the channel instead of the basket.

The fee stack on a $30 sale, side by side

Amazon Handmade charges a 15 percent referral fee, roughly $4.57 on this order (Amazon Handmade fees). Etsy charges 6.5 percent transaction plus payment processing, plus, if you are opted in, Offsite Ads at 12 or 15 percent of that specific sale (Etsy Seller Handbook: Fees & Payments Policy). All-in, expect roughly 10 to 13 percent, or $3.05 to $3.94. eBay works out similarly at around 13 percent on this category, roughly $3.94 (eBay selling fees). A direct Shopify sale on the same order takes about $1.27 in card and platform fees. The delta between marketplace and direct is essentially your entire net margin on a second candle.

What Amazon, Etsy and eBay actually forbid

Before the tactics, the reality. The naive advice, drop a 20 percent off code in the box that only works on your website, is against Amazon's seller policies and can put both Amazon and Etsy accounts at risk. Amazon in particular has a long-standing policy against inserts that divert buyers off-platform, and sellers do report account action over exactly this kind of flyer (see Amazon's Seller Central policies on customer communication and external URLs, and countless post-mortems on r/AmazonSeller). The rules, in plain English:

Amazon. No inserts, flyers, stickers, packaging copy or QR codes that direct the customer to any other place they can buy. A brand-only thank-you card with your name and logo is tolerated. A URL, a discount code, or a social handle used as a sales channel is not. Enforcement is real and the penalty is account suspension.

Etsy. No inserts that solicit off-platform sales for items the customer could have bought on Etsy. Brand cards, care instructions and safety information are fine. A newsletter opt-in via QR code sits in a grey area that Etsy has not aggressively enforced but reserves the right to.

eBay. Similar in spirit to Etsy, weaker enforcement in practice, but the same do-not-divert rule applies to identical products the buyer could purchase on eBay.

The job of this section is not to help you break those rules. It is to show you exactly where the line is, then use every inch of the compliant side.

The compliant playbook, four tactics that stay inside the rules

First, brand-first packaging. The insert says who you are, not where to buy. Your website URL appears once, small, as a made-by line at the bottom, the same way a book prints the publisher's name on the spine. No shop URL, no discount code, no call to action. The customer who wants to find you again can. The platform has no case against you.

Second, the care-and-safety QR code. Every candle already ships with a care card (see the earlier Care Card section). Point the QR code at a care guide page on your own site, not at a shop page. That care page carries an email opt-in for a burn-tips newsletter. The customer opts in on your list voluntarily, at their own initiative. Six weeks later you can email them a direct-site discount without ever having put a code in the box.

Third, the refill programme as a migration path. Refills are direct-only by operational necessity, the customer has to send the vessel back or bring it in. That is a legitimate reason to require a direct purchase and it is a Trojan horse for getting a marketplace customer onto your site. Mention refills on the care card. Do not price-anchor against the marketplace listing.

Fourth, the second-purchase email through the platform's own messaging. Amazon Handmade and Etsy both release the buyer's contact channel for order-related communication. A six-week how-did-the-candle-burn message is order-related. A PS at the bottom mentioning your direct site is a grey area that most sellers get away with. A full marketing email with a discount code is not. Know which one you are sending.

Size the direct-site discount to the fee, not to a round number

When a marketplace customer does land on your direct site, the first-order discount code should be sized to the fee you would have paid, not to whatever feels generous. On a customer who came from Amazon, a 15 percent code is break-even for you and feels significant to them. Twenty percent is a gift you did not need to give. Ten percent is invisible.

The formula. Direct-site first-order discount equals the marketplace referral fee for the channel that customer came from, rounded to the nearest 5 percent. Amazon Handmade customers get 15 percent. Etsy customers get 10 percent. eBay customers get 15 percent. Word-of-mouth customers get no code because you paid nothing to acquire them.

The lifetime-value maths that make this worth doing

Worked example. A customer acquired on Amazon who buys twice more on Amazon nets you roughly $23 across those two reorders after fees, postage and COGS. The same customer migrated to direct on the second purchase, using a 15 percent direct-site code on the first direct order, nets roughly $30 across the same two reorders. That is $7.62 per customer.

Ten repeat customers a month migrated across a year is $914 of pure margin recovered from work you were already doing. Fifty repeat customers a month is $4,572 a year. The fee is not a tax, it is a budget, and the budget belongs in the hand of the customer who has already decided they like your candles.

When to leave the customer on the marketplace

The honest counter-note. Not every marketplace customer wants to be migrated. Amazon Prime shoppers value the returns policy and free next-day delivery, and will often churn if pushed to a direct site with slower postage. Gift buyers picked Amazon because the recipient can return the item easily. Customers who found you via marketplace search, rather than a recommendation, may not remember your brand name a month later even if you did everything right. Migration is a tactic for repeat buyers who already like the product, not for first-time strangers.

The marketplace fee is the rent you pay to be discovered. Once the customer knows your name, stop paying it.

Section 09

Bring the vessel back. When it works and when it burns cash.

The customer instinct is right, the naive execution loses money on every parcel. Here is the honest version of the take-back programme.

Customers ask about this a lot. The jar is pretty, it feels wasteful to bin it, and a discount for returning the empty seems like a clean win for the maker, the customer and the planet. The instinct is right. The naive execution, a prepaid return label and a code in the box, loses money on every parcel. This section is the honest version of the take-back programme, sized for a maker without a warehouse.

The one number that decides this

Keap Candles ran a beta glass-return programme with prepaid return labels for subscribers, then published a remarkably transparent post-mortem on their own blog (Keap Candles, Rethinking our glass recycling program). Their disclosed cost per returned vessel: about $7.62 for the return label, $6.35 to $7.62 of staff time to unpack, clean and process, and roughly $2.03 of reclaimed glass value at the far end. Net loss per returned vessel: roughly $10 to $13. They paused the programme. Everything below is downstream of that one number.

The four models, ranked by what actually works

The chart on this spread is the whole argument in one image. Mail with a seller-paid label burns cash on every parcel, as covered above. Mail with a customer-paid label sits near zero not because the economics are good but because almost nobody actually posts glass back once they see the postage cost. Local drop-off with customer pre-cleaning, the model Chez Lapin moved to after the labour of cleaning jars overran their pouring time, produces a small positive margin. And the wax-insert refill, where the customer keeps the vessel and you ship a fresh pour, is the only model with real margin because no glass ever moves through the postal system.

Three UK and EU rules people get wrong

A refilled vessel is a new product placed on the market. Under GB CLP and EU CLP it needs a fresh classification, labelling and packaging pass matched to the exact pour (HSE, GB CLP regulation; ECHA, CLP Regulation), printed for that specific refill and applied over or in place of the original. You cannot reuse the label that came with the first candle. The label generator at /tools/clp-label-generator writes a fresh label per pour, which is the pattern to follow.

Candle glass is not manufactured to food-contact standards. Marketing your vessel as a drinking cup, a wine glass or a tumbler implies a compliance claim under the framework food-contact regulation (EU Regulation 1935/2004 on materials intended to come into contact with food; retained in GB law post-Brexit) that you almost certainly cannot substantiate. Repurpose-as-a-planter, pencil pot, or tealight lantern is fine. Repurpose-as-a-wine-glass is not.

The UK CMA Green Claims Code (CMA, Green Claims Code guidance), and from March 2026 the EU Empowering Consumers Directive (Directive (EU) 2024/825), require environmental claims to be truthful, substantiated, and specific. Blanket phrases like eco-friendly, zero waste and sustainable are the ones being enforced against. Say what you actually do (bring your jar back and save $3.81), not what you wish it meant.

The two models we recommend

For an online-first maker, the wax-insert refill is the model that works. The customer keeps the vessel. You send a pre-poured wax cartridge or you refill in studio when they bring it in. No return postage, no cleaning at your bench, no risk of a smashed jar arriving in a Jiffy bag. The refill is priced around 55 to 65 percent of the original candle, which passes real savings to the customer and still nets you more per unit than a fresh pour because you have removed the vessel from the cost stack.

For a maker with regular markets or a studio open to the public, local drop-off is the model that works. Customers bring the empty jar back to a stall or a shop counter. You require it pre-cleaned, no wax, no wick tab, no soot. You give a modest thank-you (10 to 15 percent off their next purchase, or a straight $2.54 credit) and re-use the glass on your next pour day. No postage cost, no cleaning bottleneck, and the in-person handover is a retention conversation you would not otherwise have.

How to price the refill discount

Reuse the fee-recovery formula from the previous section. The vessel is a line on your COGS. Refill price equals the original price minus the vessel share minus a small thank-you for the customer effort. On a $30 candle with a $3.81 vessel, a refill priced at $20 keeps roughly $6.35 of that saving as maker margin and hands the customer roughly $10 in return for the loyalty. Do not over-discount because it feels generous. The customer is already showing up for you.

Say this. Not that.

Language matters more here than almost anywhere else in the book, because the CMA and its EU equivalent are actively enforcing against overclaims. Safer phrasing: bring your jar back and save $3.81, refills use the vessel you already own, we keep glass out of landfill. Riskier phrasing: eco-friendly refill programme, zero-waste candles, sustainable packaging. The difference is that the safer phrases describe what you do, the riskier phrases imply an environmental benefit you cannot substantiate without an LCA you have not commissioned.

The take-back programme that works is the one where the vessel never gets in a parcel. Refill in studio, refill by post with a cartridge, or drop off at a market. Everything else loses money and calls it green.

What NOT to upsell

The add-ons that look easy from the outside but carry regulatory, storage or brand costs that eat the margin they promise.

Not every logical add-on is a good one. These are the ones that look obvious but carry a hidden cost that eats the margin they promise. Skip them until the core AOV work above is running smoothly.

Room sprays

A room spray uses the same fragrance oils as your candles but is regulated as a different product category. In the UK and EU it needs its own CLP label, its own PCN submission, and often a different flashpoint safety data sheet from the same supplier. In the US it may cross into consumer product regulation depending on claims. Your candle insurance policy almost certainly does not cover it. Add room sprays only when you have the compliance appetite to redo the label studio work per SKU.

Reed diffusers

Reeds use a different carrier base (typically DPG or a dedicated diffuser base rather than wax), which means a different SDS, a different flash point, and often a different allergen calculation. The regulatory work is not double, it is a second complete pass. The margin per unit is thinner than candles because glass and reeds are more expensive per finished piece than a candle jar.

Anything requiring a separate SDS you do not have

The rule of thumb: if the supplier of the raw material publishes a different safety data sheet than the one you use for your candles, treat that add-on as a new product category. That is not a reason to avoid it forever. It is a reason to do the compliance work before you list it, not after.

The upsells that work are the ones that use the same fragrance, the same wax pot, and the same insurance policy. Every other add-on is a second business pretending to be an add-on.

That closes Act 4, and with it the Codex. Pour honestly. Test hard. Price without flinching. Label like an inspector is watching. And get a second unit into the same shipment, because that is the number that turns a candle habit into a candle business.
