My JoAnn's store tells me only one coupon per item. So if you use say a 40% off you can not combine it with the extra 25% off on that item. It is something to do with their computer system because they have tried to over ride it before. Even if they have to do a price adjust it will not take the extra 25% off. So, I always shop the sale items and use my coupon for those things. Also, most of my coupons always say they exclude the GO products but they work on them anyway. The ladies at our store try and use every coupon even if they don't think it will work. They are great! I even had one of the clerks give me some Elvis fabric for a project I was working from her own private stash!
