The last time I was at Joann's, I got 2 of the 25% (off your total order) coupons at the check-out counter. Each one has a coupon for you and one for a friend. Even though I am on the mailing list and did receive this week's sale ad, I did not get a 25% coupon in the mail.
I am going tomorrow with a gift card and some cash I got for my birthday. I need sewing machine needles, thread, spray adhesive and a whole bunch of fabrics. (I do Quilts for Kids). We'll see how well I do!
