I use the coupons for battings, cutter blades, needles and often thread, especially serger thread.
I only go to JoAnns when I really need these things and ONLY with coupons. It is a long drive to closest one. Not particularly unhappy with this as I do not buy the fabric there. Work in a couple LQS and get my fabrics at employee discount. Also need to support LQS. Don't want them closing.
