Walmart offers the Orion 4-Shelf Bookcase in Black or Oak, model no. 42344, for $19.88. Opt for in-store pickup to dodge the $4.97 shipping fee. That's a buck under our mention from two weeks ago and the lowest price we could find in any color by $9. It measures approximately 25" x 9.5" x 47.5" and features a protective kick plate, adjustable shelves, and back panel.
