I take them with me and try to use them every time. Normally, they are not usable because everything is a sale item. However, just this past weekend, I went to buy a few miscellaneous items (fusible fleece and fusible interfacing - decor bond), plus a couple of spools of thread. Ended up being able to use both my weekly coupon AND the one I receive through their mailing. Absolutely NOTHING I purchased that day was on sale!
Joann's is the only store where people complain that items are on SALE. Hilarious!! :D
