I signed up two or three times before I finally started receiving the flyers; but they do keep coming if you make sure to have your bar code scanned whenever you are there. Needless to say, I keep the flyers in my purse at all times so I can't forget them when the Joann's stop fits in with our other errands.
One time I was in the checkout line, and the shopper behind me asked if I had any more coupons she could have. Wow! That's a little nervy! I would offer a coupon to someone else if I knew I couldn't use it before the expiration date, but I would never ask someone for a coupon!
