# Order Discount

> Apply discounts at cart-total level with spend rules, product-based triggers, and exclusions for protected collections.

Order Discount applies savings to eligible cart totals rather than to specific item lines.

## Best Use Cases

* Spend-threshold promotions
* Cart-level conversion incentives
* Broad campaigns with exclusion controls

## Common Structures

* Spend X, get amount off
* Spend X, get percent off
* Buy X, get order-level discount
* Advanced order discount conditions

## Key Controls

* Cart threshold or product-trigger requirements
* Excluded collections (margin protection)
* Mixed-cart behavior (eligible vs excluded lines)
* Priority interplay with item-level discounts

## Example

<Callout>
  Offer: buy 1, get 10% off order. "New Snowboards" excluded.
  If cart contains only excluded items, discount does not trigger.
  If cart is mixed, discount applies only to eligible items.
