I have a 10% discount card from Quilters Club of America that is good for 10% off the entire bill at Joann's (sale & regular prices) and my local Hancock's will accept it too.
My best buy was a couple weeks ago when Joann's had 50% off of W & N batting, $5.49@. I wanted a whole 40 yard roll but they were out so they special ordered it for me (same sale price) plus I got my additional 10% off. Price ended up 60% off! I was in heaven! lol
