At the JoAnn's closest to me, you can use a coupon if you take the % off the regular price and not the sale price. If the coupon is 40% off and the item is on sale for 10% off then I use the 40% off coupon taken off the regular price. Hobby Lobby does this so JoAnn's started doing it here too. All Joann's should do the same thing. Some managers aren't afraid to do what they can to keep customers and keep profit up, some say Oh I'm not allowed to do that.
