I downloaded JoAnn's app for my iphone sometime ago in anticipation of the new JoAnn's opening the end of June.
I went to the store once right after they opened, Purchased one small thing just to get the coupons they gave you for my next trip. Well of course today was my next trip and I forgot the coupons! BUT.... I opened the app and it has coupons on there for the week. You add to your "wallet" and then just call it up when you check out. The cashier puts in the code number from the app coupon! I had five to choose from! Super easy, no paper coupons to remember! Wonderful thing this technology! lol Also found the perfect piece of fabric by searching their site on my phone.
