They cannot keep your other coupons especially if you can't use them they have to give them back. I would go back and talk to the manager and tell them other joann's take the coupons why not you. That is false advertising and you should call the head office.I hate when I have a coupon then go in the store and things are on sale for least then the coupon and now you can't use it before you could, what a waste of time and paper....
