Do Bed Bath and Beyond Coupons Expire? While all of their coupons have expiration dates, these dates rarely mean that the coupon cannot still be used. When shopping at the store, cashiers regularly ignore the expiration date and still ring up the discount. The expiration dates encourage shoppers to shop regularly at the store, but can probably still be used. So, if you have a stack of expired coupons from the mail or newspaper, keep them for your next trip instead of throwing them away. While a store does not have the right to refuse acceptance of an expired coupon, it’s extremely rare for Bed Bath and Beyond to not use these expired coupons.
