Shopping cart price rules create discounts for orders at the checkout level, based on a set of conditions. The discount can be applied automatically when the conditions are met, or be applied when the customer enters a valid coupon code. When applied, the discount appears on the shopping cart page under the subtotal.

Once established, the price rule can be used permanently or between a specific set of dates by changing its status and date range.

Accessing Shopping Cart Price Rules

From the Admin menu, select Marketing - Promotions - Cart Price Rules
