Walk down the snack aisle of any supermarket and you will see quantity pricing at work: one bag for $4, three for $10. Online it is the same instinct. A quantity break gives shoppers a better unit price for committing to more units, and for products people use up and buy again, it is one of the most dependable ways to grow order size on Shopify.
This guide covers what Shopify gives you out of the box in 2026, where the native tools stop, how to set up tiers in a few minutes, and the margin math worth running before you pick your discounts.
What quantity breaks are (and where they work)
A quantity break is a tiered discount on the same product. Buy one at full price. Buy two, save 10%. Buy three, save 15%. The shopper sees every tier at once on the product page, and that visibility is the whole trick: the better unit price appears at the exact moment someone was already going to buy one.
The format suits anything a customer will eventually need more of. Coffee, candles, socks, supplements, pet treats, skincare they have already tried. It also works for gifting seasons, when one good product quietly becomes three presents.
It is much weaker for true one-off purchases. Nobody needs a second paddleboard at 10% off. If your catalog is mostly buy-once items, fixed bundles of complementary products will usually do more for you than quantity tiers.
What Shopify covers natively in 2026
Shopify has closed part of this gap over the years, so it is worth knowing what you already have before installing anything.
Discounts with a minimum quantity
In the admin you can create an amount-off discount that requires a minimum quantity of items. It works, but each discount holds a single tier, so a three-step ladder means three separate discounts plus combination rules. The bigger problem is that shoppers cannot see any of it on the product page. The deal surfaces in the cart, after the decision it was supposed to influence.
B2B volume pricing
Shopify's B2B catalogs support proper quantity price breaks, and this feature has been reaching more plans over time. The catch sits in the name: it applies to logged-in customers attached to a B2B company profile. Your regular retail visitors never see those prices, so for a D2C store this solves a different problem.
Shopify Functions
If you have a developer, Shopify Functions let you build custom discount logic with full control. It is the right path for genuinely unusual pricing rules, and overkill for "buy 3, save 15%".
The piece all three are missing is the storefront. A tier table on the product page, with the saving spelled out per tier, is where quantity breaks actually earn their keep. That is the part an app adds.
Setting up quantity breaks in Bundlex
Here is the short version of a setup that takes about five minutes:
- Create an offer and choose the quantity break type. One offer covers the whole tier ladder, so there is nothing to stitch together later.
- Add your tiers. Two is a fine start, for example 2 units at 10% off and 3 units at 15% off. Our help article on how offer tiers work walks through every field.
- Pick where it shows. Target single products, whole collections, or everything except a list of exclusions. See targeting products and collections for the options.
- Check the widget against your theme. The tier table picks up your fonts and colors automatically, and every label can be edited, so "Most popular" can become whatever your brand would actually say.
- Preview and publish. Before going live, decide how the offer should behave next to discount codes, and read up on stacking with other discounts so a welcome code does not pile onto your deepest tier.
Pricing your tiers without giving away the margin
Tier percentages get picked by gut feel more often than anyone admits. Run the numbers once and the right discounts usually become obvious.
Say you sell a $32 candle and your all-in cost per unit is $11 once the product, packaging, and a slice of shipping are counted:
- One unit at full price: $32 in revenue, $21 of profit.
- Two units at 10% off: $57.60 in revenue, $35.60 of profit.
- Three units at 15% off: $81.60 in revenue, $48.60 of profit.
Your margin rate falls with each tier while the cash per order grows. Both of those are fine, because the alternative was not three orders at full price. It was one order, and a paid-ads bill for chasing the next two. A sensible floor for your deepest tier: the extra profit it brings in should still beat what you normally spend to win one more order.
One more pricing note. The crossed-out anchor next to each tier should be the genuine single-unit price, nothing invented. It converts well because it is verifiable, and price transparency rules in several markets require it anyway. Bundlex reads this from your product's own pricing, see how compare-at prices work.
Mistakes that quietly eat the results
- Too many tiers. Five options is a spreadsheet, not an offer. Two or three tiers outsell longer ladders in almost every store we see.
- Tiers that ignore how the product is used. If customers go through one bag of coffee a month, "buy 6" is asking for half a year of commitment. Match tiers to a realistic stock-up, not to a warehouse clearance.
- Discounting the first unit. Tier one should stay at full price. A discount on quantity one pays people for what they were doing anyway.
- Ignoring discount stacking. Decide before launch whether codes combine with tier pricing. Finding out from a margin report is the expensive way.
Measuring whether it works
Give the offer two to three weeks, then compare against the period before. Three numbers tell most of the story: average order value, units per order, and profit per order. A tier table that lifts AOV but drags profit per order below where you started is just a discount with better typography.
Look at which tiers people actually choose, too. If almost every discounted order stops at the first tier, the jump to the next one is probably too steep, in quantity or in price. Adjust the quantity before you touch the percentage. In our experience the tier amounts are wrong far more often than the discounts are.
Quantity breaks will not double your revenue by Friday. What they do, set up carefully on the right products, is raise the value of orders you were already getting, every day, without another dollar of ad spend. That compounds.
