The closest WalMart in Sierra Vista, AZ does still have material and a wonderful staff...
The one in Benson (which is a super walmart) does, but everytime ive been there, the 1 staff member working in it has ignored customers standing there in order to have personal conversations... last time i was there, i gave up and left with nothing after standing there holding 3 bolts for almost 45 minutes. But somehow ended up knowing more about her family than my own lol
