I registered with this site and recieve updated coupons as they are made available. So far I have not had any problems using them. Note, there are on-line codes as well as printable. -- I am also registered with Joann's on-line, and they send me their add with printable coupons. I wasn't able to attch that link with the coupon, so if you register, you may get the printable coupons as I do.
