A. C. Moore seem to me to be less obnoxious than either JoAnn's or Michael's. I'm not sure why because they do carry pretty much the same stuff but it just seems a little nicer somehow. There's always a flyer in Tuesday's mail with a coupon good for 40% off one item and I think they take competitors' coupons, too. They have cheap matboard in the art department (not archival). I go here mainly when I happen to be at this shopping center for other stuff.
The store is crowded and sometimes untidy. Lots of parking unless you are there on Friday or Saturday evening, then forget it.
