Cart price rules
Cart price rules apply discounts to items in the shopping cart, based on a set of conditions. The discount can be applied automatically when the conditions are met, or when the customer enters a valid coupon code. When applied, the discount appears in the cart under the subtotal. A cart price rule can be used as needed for a season or promotion by changing its status and date range.
NOTE
If the coupon cart rule has conditions that specify checkout options, such as certain shipping or payment methods, the conditions are met only in checkout after the specific shipping/payment methods are selected. In this case, the coupon can be applied at checkout in the last step.
