Apropos of nothing

It turns out that those "low-low" Walmart prices are just an illusion. In fact, they offer cut prices on a handful of things that people buy frequently enough that they know a discount when they see it, and then the rest of the stuff they sell at average or higher prices (and you just extrapolate from, say, the cheap milk to the assumption that "everything is cheap here"). So it's not just the employees getting screwed...
