Effects of Coupons on Consumer Purchase Behavior: A Meta-Analysis

77% of the United States population uses coupons and shoppers saved more than $3 billion last year by doing so. Coupon users report an average of 11.5% savings on their grocery bill with coupons, prompting manufacturers to respond by offering more than $250 billion in coupon savings in 2003. No doubt, therefore, that ‘coupons’ have been investigated extensively, and from a very divergent perspective (Chatterjee et. al 2000; Cheema et. al 2002; Heilman 2002).
