Discount value and eligibility

Choose which items are discounted and by how much.

This section of the form defines the discount itself: which line items it can touch, and the value it applies.

​

Discount eligible products

Narrow which line items the discount can touch. You can also exclude products in the same way.

Rule	Selects line items by
Product ID	Specific products
Product collections	Collection membership
Product type	Product type, for example skincare
Product vendor	Vendor name
Variant SKU, ID or title	Specific variants
Cheapest / most expensive product	The cheapest or most expensive item(s) in the cart
Has selling plan / has not selling plan	Subscription or non-subscription products
Compare at price	A compare-at price condition
Product tag	Product tags (advance input only)

Use single mode when one rule is enough. Multiple mode combines up to three conditions in one rule.

​

Discount to apply

Value	Effect
Percentage discount	A percentage off each eligible item
Fixed total discount	A fixed amount off the eligible items in total
Fixed discount per item	A fixed amount off each eligible item
Fixed discount per quantity	A fixed amount off per unit
Fixed price	Sets eligible items to a fixed price
Dynamic price	Per-variant, customer-segment and time-window pricing (advance input only)

​

Discount target

Choose Variant target (the usual choice) or Cart line target.

Volume campaigns replace this section with a tier editor: set a quantity threshold and a value for each tier.
