Did you know that Joann's has text message coupons and alerts? It is really nice. I get two mailers, and an e-mail and usually they all have coupons. I don't have to print off the e-mail because there is a "text it to me" option that I use and the store people are really friendly about it.
I usually use the 50% off coupons because they are the best deals but if I'm really in a pinch I use a 40% one.
Also Hancock Fabrics and Micheal's both take The %off coupons from Joann's! Keep this in. Mind there is something that you really want from those two stores, as well.
