Do you receive those 20% off Bed Bath & Beyond coupons in the mail as frequently as I do? If so, you should keep them instead of throwing them out when they pass their expiry date. BB & B will honor them even past the expiration date that is printed on it.
I was let in on this little secret by a friend and actually asked the staff at Bed Bath & Beyond in San Francisco to double check the rumor. I was informed that, yes, they will still accept the expired coupons. Sweet! I'm going to make a little stack of these in the future.
