Walmart offers the Mainstays 5-Shelf Standard Wood Bookcase in White for $24.99. Opt for in-store pickup to dodge the $5.99 shipping charge. That's $3 under our mention from a year ago, the lowest price we could find now by $12, and the best deal we've seen. It has five shelves and measures 71" x 30" x 12". Note: It's available in several other colors for $27.44.
