Add Coupons Wizard
Use the Add Coupons Wizard to add coupons to a discount. Coupons are used as an eligibility requirement for the discount. One or more unique coupons are associated with a discount. When shopping on the Web site, the user enters a coupon code, and the corresponding discount is applied, if the other discount conditions are met. You can use coupon definitions when adding coupons. These specify how many times the coupon can be used, and whether the coupon will be public or private.
