I had a problem with one I bought on their regular sale. W hen I went to attached the top to the base the screw holes were striped or too big, so it wouldn't hold. Also one side of the top was damaged. I called the store and explained the problem and that I had it mostly together already. They had me bring my receipt and the damaged pieces and replaced them with new pieces out of another box. That way I got to check out the replacement pieces. I've had it for 4 years now and love it. So contact Joann's and talk with a supervisor. It would be terrible to have to take whole thing back. Good Luck!!
