Oh, that's marketing bullshit.
I never saved a goddamned cent at Wal-Mart and anyone who says that they have are either lying or in denial.
Kind of like the folks who believe in Jesus. 
But Wal-Mart carries the pants that I buy, and has cheap underwear! 
Everything at Wal-Mart is cheap. Most of it is Chinese. This isn't a myth, they bring down their prices by buying in bulk and leveraging for discounted wholesale prices. I have no idea what you are going on about, as usual Dook.
I don't shop there because I absolutely despise the place, but I could save a few bucks if I did.
