Yes, sometimes they will give you the better deal depending on which store you go to. Some Joanne's will do the better deal, and some won't. You just have to know where to go.
I usually keep the entire ad in my purse and coupons and go for what I get. I always try to use my coupons as much as I can and as some of the other ladies suggested, use the extra coupon on something that usually does not go on sale. :)
