Always Low Prices? Wow!

We all know that Walmart (formerly Wal-Mart) advertises low prices. However, if this isn't a mistaken sign posting, it has finally gotten to the point of being free. This was an end cap display of plastic bins for storing holiday decorations that I saw today at the Stafford, Texas store. What next? Maybe negative prices, meaning they pay you to take merchandise? Well, probably not.
