Walmart offers the HyperTough 2-Drawer Roller Seat for $50.75. To drop the price to $48.87, opt for in-store pickup. That's $4 under last week's mention of a shipped unit and the lowest price we've seen. (It's also the best deal we could find today by $16.) It features a padded seat, loose item shelf, four rolling casters, and two push-open drawers.
