I never have any of these problems. I get Joann's in my regular email, and also in a text message. Either way, I click on "Get Coupons" and they all come up, usually about 6 and the cashier scans the ones that apply to my purchase. Sometimes the scanner doesn't pick up the bar code, and we have to stretch the bar code open or enlarge it a bit, and then sometimes the cashier just enters the barcode number and gets it that way. I don't even want the Joann's app..
