Both our Wal-Marts have fabric. The older superstore discontinued their fabric but then brought it back....after many protests, I'm sure, and perhaps lost sales. The newer superstore (two years old) included a fabric section from the beginning. Both stores have nice fabrics, same quality and often same fabrics, as JoAnn's. The problem is they have no dedicated fabric salesperson and so it's always a mess. When I go there, sometimes it's all I can do not to try to bring order and tidy up the bolts!
But the prices and selection are good, so I continue to shop for fabric there.
