I don't know why I bother going to Wal-Mart for anything home-improvement related. Their customer service sucks and they never have what I need.
A couple of weeks ago, our toilet started refilling the reservoir tank intermittently. By intermittently, I mean every 2 minutes. All night long. So I decided to replace some components in the tank. Unfortunately, the shut-off valve was corroded and needed to be replaced. Drat! My initial trip to this Ace involved me thinking I was too smart to ask for assistance. The end result was going home with the wrong shut-off valve, the wrong fill valve and a too-long supply hose. By the time I realized this error, it was too late to return to the store and get the right items--hence, the Wal-Mart revelation. When I was able to return to Ace, I asked for assistance. They were able to exchange the wrong items I picked up for the right supplies, and did it with a smile. I even was able to get some keys cut at the same time. Sweet!
