In 2010, U.S. consumers redeemed 3.3 billion coupons, cutting roughly $3.7 billion from purchase prices. That’s a lot, particularly since only about 1% of all coupons are ever used. Conventional wisdom holds that manufacturers and retailers see little benefit from the other 99%. But new research suggests that unredeemed coupons are highly valuable. In fact, the coupons that wind up in the trash ultimately deliver greater returns to a company than the coupons that are redeemed.
