Strange that this thread pops up today. Before yesterday, I hadn't been in a Walmart in years, ever since I decided that the cheap prices for crappy products weren't worth supporting this anti-union, employees on welfare, basically sucks in every way, evil empire.
Then, at about 9:30 last night, I managed to break both my wiper blades chipping about 1/2" of ice of my windshield. Walmart was the only place open that was close enough to drive to while peering out through the tiny hole in the ice.
Remarkably, they had the right size wiper blades in stock. If I'm lucky, it's the last $12 they ever get from me.
