Rule types
Amount Off rules
Discount specific variants by a percentage or fixed dollar amount.
Amount Off is the most common rule type. It applies a percentage or fixed-dollar discount to every variant matched by your conditions.
When to use it
- Seasonal sales on a collection ("All summer items 20% off")
- Inventory clearance on slow-moving SKUs
- Tag-based promotions ("Everything tagged
vip15% off") - Variant-level targeting that Shopify's native discounts can't handle (e.g. "Only red and blue variants")
Configuration
| Setting | Description |
|---|---|
| Discount type | Percentage (%) or Fixed amount ($) |
| Discount value | The number — e.g. 20 for 20% or 5.00 for $5 off per matched item |
| Applies to | The variants your conditions match (set in the condition builder) |
| Method | Automatic or code-based |
How the discount applies at checkout
For each matched variant in the cart, the customer sees the line item discounted by the specified amount. Multiple matched items in the same cart all get the discount independently.
If the cart contains items the rule doesn't match, those are charged at full price. Only matched variants are discounted.
Examples
Percentage discount on a collection
Discount: 25% off Conditions: Collection is "Summer 2026" Result: Every variant in the Summer 2026 collection is 25% off at checkout.
Fixed-amount discount on tagged products
Discount: $5 off Conditions: Tag is "clearance" Result: Each item tagged
clearanceis $5 cheaper at checkout.
Variant-specific discount
Discount: 30% off Conditions: Color is one of "Red", "Blue" AND Size is "XL" Result: Only the Red XL and Blue XL variants are discounted.
Combined with other discounts
By default an Amount Off rule doesn't combine with other discounts. To allow stacking (e.g. with a sitewide order discount or a shipping discount), enable the appropriate combination in the rule's settings. See Discount combinations.
Limits
Each rule respects Shopify's 100-line discount limit. Use the live counter while building to stay within the cap.
