Using Expired Grocery Coupons
You can still use an expired grocery coupon, as many stores have an unofficial grace period if you ask politely.
When cleaning out your wallet, you may find a great coupon that you forgot to use, only to discover it expired yesterday. However, most people throw away these coupons, assuming they are worthless. In many cases, this is not true.
A surprising number of major retailers have an unwritten and unofficial “grace period” for their coupons. By being a polite and savvy shopper, you can often still use a coupon that is a few days or even a week past its expiration date.
They would rather keep a loyal customer happy than argue over a 50-cent discount.
Many large retail chains empower their cashiers and managers to accept recently expired coupons as a gesture of goodwill. This unofficial grace period is usually for about one week after the coupon has expired, providing excellent customer service.
