When I read this post I got up off my couch and walked the 1/4 mile over to the super Walmart. Unfortunately, these wrenches are still $49 there (on sale from $59).
I normally avoid Walmart (the only things I buy there are 9mm ammo and synthetic motor oil), but I already have one of these wrenches and I really like it. It's great for running fasteners in or out. I still use a real wrench to tighten or loosen things.
But last weekend I grabbed the wrench out of the charger, and it was non-responsive. Clicking the button does nothing. The green light comes on in the charger, but the wrench doesn't work.
I want another one, but apparently my price point is somewhere between $49 and $19. And I don't feel like going back to Walmart to check on an updated price.
