to purchase. WebSphere Commerce supports
numerous types of promotions. For example, price promotions that include
offering simple discounts; merchandise specials such as gifts with
purchase and buy-one-get-one. More service promotions are available
that include offering reduced shipping costs. Business users create and manage promotions with the Promotions
