How do I set up a Volume discount?

Updated November 2, 2026 · SMART Bundles App & Upsells (E-TRADE PARTNER)

Click Create new discount, pick Volume discount under Other discount types, choose what it's Based on, the products, and up to 10 Tiers. In the cart and at checkout, the highest tier the cart reaches applies to every qualifying unit. Nothing shows on the product page.

Step by step

1. In SMART Discounts, click Create new discount and pick Volume discount under Other discount types.
2. Enter a Discount name and choose the Application method: Automatic or Code. See Automatic or code, and schedules.
3. Under Based on, choose Product quantity (units) or Product price (amount spent).
4. Under Products, set Any items from: Products, Products other than, Variants, Variants other than, Collections, Collections other than or All products, then pick them. Set Purchase type to Any, One time purchase or Subscription purchase. Tick Exclude products with compare at price (already on sale) to skip sale items.
5. Under Group by, choose All products, Product or Variant (see below).
6. In Tiers, enter the Required quantity (or Required amount), a Discount label (automatic discounts only; code discounts show the code at checkout), the Discount type (Percentage off, Amount off per item or Fixed price per item) and the Discount value. Click Add tier for more, up to 10.
7. Check Purchase types, Combines with, Eligibility, Active dates and, in the right column, Conditions. Code discounts also get Maximum discount uses. Click Create.

How the discount is calculated

• Only one tier applies: the highest tier reached, to every qualifying unit. Lower tiers don't stack, and the first units don't keep a lower tier's price.
• Group by decides what counts together. All products: every qualifying item counts toward one tier. Product or Variant: each product or variant reaches its own tier.
• Product price tiers use the amount spent on qualifying items, before other discounts. Shopify's discount functions run at the same time and don't see each other (Shopify developer docs).
• Percentage off comes off each unit. Amount off per item takes that amount off each unit.
• Fixed price per item sets each qualifying unit to that price. If a unit already costs that or less, it gets nothing: a discount never raises a price.
• Already on sale means the item's compare-at price is above its price.
• There's no cap on units: every qualifying unit gets the tier.
• Amounts are in your store currency and converted at Shopify's rate for other currencies.

Example

With Group by set to Product, the last cart would give the shirts 10% (3 units) and the caps 10% (2 units).

Limits and edge cases

• Nothing on the product page. Shoppers see the saving in the cart and at checkout. To show tiers on the product page, use a bundle with Quantity breaks: see Quantity break tiers.
• Subscriptions. Applies on subscription purchases is off by default, and then a cart holding any subscription item gets no Volume discount at all. Turn it on in Purchase types if you sell subscriptions.
• Variants. Picking a product includes all its variants. To target only some, choose Variants.
• Collections are checked at checkout, so products you add to a collection later qualify without editing the discount.
• Another product discount on the same items: Shopify applies one product discount per line item unless your store is on Shopify Plus (Shopify Help Center). See Combine with other discounts.
• Still not applying? See Discount not applying.
