Money is everyw here. People throw it away everyday.. Don't believe me? Last time you went to the grocery, what did you do with your receipt? Throw it away, right? Some local groceries, like Buehler's, has advertisements and coupons printed on the reverse side of your grocery receipt. My latest grocery receipt has coupons for $4 off $20 at Tequilas, $2 off a car wash, $1 "Spud Buck", discounts for haircuts, 15% at Kid's Consignment, and discounts at Fazoli's. Next time, flip it over.
