All my coupons say that they are only good in store.
If you go to retailmenot.com and input bedbathandbeyond.com in the search, the page will come up for offers for that store. They seem to have free shipping on some K-Cups right now. It's better than nothing.
Did you know (in my state anyway) that Bed Bath and Beyond coupons never expire? I just used some from 2003 yesterday. (I keep them in my car in an envelope because I don't buy anything from BBB without a coupon.)
That's why I always keep all of mine. However, BB&B has changed their coupons. The new ones come out with 20% off if used by a certain date. After that date, it's only 10%, but it's 10% forever!
Here on Long Island they give the full 20% and you can use one for each item you are purchasing! I also keep mine in an envelope in the car because they never expire.
