These schemes offer discount coupons for buying a specified range of products or a specified quantity of products. Some manufacturers give their own coupons which are in addition to the coupons issued by the super market. For example, a dog food manufacturer may sponsor a $1 discount coupon as an advertising strategy. The supermarket may advertise another $1 discount on every $15 worth of dog food. The customer can redeem both the coupons and pay only $13 for the dog food and thus save $ 2 on every visit.
