Walmart offers the Orion 4-Shelf Bookcase in Oak or Black, model no. 42344, for $21.13. Opt for in-Store pickup to avoid the $4.97 shipping charge. That's the lowest price we could find for any color by $13, although we saw it for $5 less in August. It features a protective kick plate, two fixed and two adjustable shelves, and measures 25" x 25" x 48".
