The parameters include a set time period, certain action by the customer, the purchase of specific items, the purchase of specific dollar values, or external parameters such as the score in a baseball game. The coupons may be transferred or recopied by the customer as desired. The customer may gain additional benefits by recopying the coupons to others. |
