Key takeaways
- A sitewide sale discounts the SKUs that were going to sell anyway. A variant-level break discounts only the ones that are stuck.
- Target the break at the variant, not the product. "Navy / M" can be 3 for 10% while "Black / M" stays full price.
- Show the break on the product page only when the selected variant qualifies. A global table that does not apply is a trust leak.
- Pair slow-moving variants with a bundle or add-on only after the break exists. Discount stacking is how clearance becomes a loss.
Clearance is usually a blunt instrument. You take 20% off a product because one colour is stuck, and you also take 20% off the colour that was going to sell at full price by Friday.
Variant-level volume discounts are the sharp instrument. The stuck SKU gets a reason to buy two. The healthy SKU is left alone.
When this is the right tool
Use it when:
- One colourway or size is overstocked and the rest of the product is fine.
- The product is a consumable or a multi-buy category (socks, candles, supplements, basics) where taking two is reasonable.
- You would rather move units than run a sitewide percentage off.
Do not use it when the variant is simply mispriced, or when the product is a single-purchase item (a sofa, a laptop). A quantity break on a sofa is a joke.
How to present it
The shopper selects a variant. If that variant has a break, a short table appears: "Buy 2, save 10%. Buy 4, save 20%." If they switch to a variant without a break, the table disappears.
A table that stays on screen for variants it does not apply to is a lie. Lies in the buy box are expensive.
Margin, not just sell-through
Work the break backwards from the landed cost of the stuck variant. If you can give 10% at two units and still sit above your floor, that is the offer. If you cannot, markdown a single unit instead — a quantity break that loses money faster is not merchandising.
Do not stack a collection sale on top. The whole point of targeting the variant is to avoid a second discount.
Inventory after it works
When a colourway starts moving, turn the break off. A quantity discount that outlives the overstock becomes the new regular price, and you will train your best customers to wait for it.
Frequently asked questions
Will customers get angry that one colour is cheaper?
Rarely, if the cheaper colour is clearly a specific variant and not a secret. Shoppers understand clearance. They do not understand a price that changes for no visible reason.
Should I use a quantity break or a markdown?
A markdown is for "we will never restock this." A quantity break is for "we would like you to take more than one." If the variant is a dead colourway you will not reorder, markdown it. If it is a size curve problem, use a break.
Can I combine this with a collection sale?
You can, and you probably should not. Two discounts on the same line make margin unreadable. Pick one mechanism per variant.
Where do I show the offer?
Under the variant picker, as a small table that updates when the shopper changes colour or size. Not in a banner that applies to the whole product.
