Check out the two receipts from my shopping excursions this week. The one on the left is from Tops and the one on the right is from Wegmans. Coupons on the back of register receipts are nothing new. Useful coupons on the back of a register receipt is new however. Congrats to Wegmans for doing it right. Their receipts now feature store coupons for products you may actually use. Notice the Tops example has the same 20 year old car wash and state auto inspection coupons. Which would you rather have?
