Cart discounts and targets

A cart discount has an eligibility rule, a target, and a value. The rule decides whether the cart qualifies. The target decides whether the reduction applies to the total, selected line items, or shipping.

Eligibility and target are separate

For example, a cart may qualify when its EUR subtotal reaches EUR 100.00. A line-item target can then restrict the saving to accessories. A qualifying cart with no matching accessory lines has nothing for that line target to discount.

A cart predicate reads the whole cart. A line-item target predicate reads one line directly, so it starts with fields such as product, variant, or quantity. See Cart predicate language.

Define the amount deliberately

Use an absolute money reduction or the documented relative factor. Pair amount thresholds with a currency condition. A threshold of 10000 has no consistent meaning across different currencies without that condition.

A code requirement, validity window, priority, or combination policy can further restrict application. Read Discount codes and combination when offers overlap.

Display applied discounts

Read the cart, line, and shipping discount applications that correspond to the target. Use Thor’s returned totals and tax values after adding or removing a code. Do not distribute a total reduction across lines with an independent frontend formula.
