A promotion code, also know as a coupon code, is a code that is associated with a marketing discount. For example, a retailer might tell frequent customers to enter the promotion code "FX43B" to receive a 10% discount on their whole order. One or more unique promotion codes (may be numbers or strings) are associated with the discount. Promotion codes act as an eligibility requirement for the discount. When shopping, if the user enters a promotion code, the corresponding discount is looked up and applied if the all the conditions of the discount are met.
There are three types of promotion codes:
Coupons that anyone can use. The coupons all use the same public coupon code.
You must import the user list for restricted coupons. The associated coupon codes can also be imported, or they can be automatically generated.
