Coupons

Coupons are a way to offer customers a discount with a coupon code. A coupon can have several discounts and exceptions. For example, a coupon discount can apply to a whole order, to particular categories, to individual products, or to shipping methods. A coupon can be limited to a maximum number of uses, by specific customer groups, by expiration date, and more.
