The store has two weeks to submit the coupons to their clearinghouse. They also make (a small amount) of money on the coupon vs. you paying in cash (unless they do doubling where they lose).
Technically they are not supposed to accept a coupon that expired 24 or 48 hours ago. But if you ask in the middle of checkout, you'd be surprised where 3 out of 4 times they will say no problem (if you have a decent cashier).
