Don't know of one off hand, but I have a sale ad for May 8-21. You may be able to go to their website to get a digital copy of the ad and the 40% off coupon that is in it. If you can't find one at Joanns.com, try to Google
"joanns coupon" and see if you can find one. While you are in town be sure to get on their mailing list so that you can get the printed ad and coupon in the future.
