Walmart offers two Ameriwood 3-Shelf Bookcases in Black, White, or Espresso, model no. 9424026PCOM, for $38. Opt for in-store pickup to avoid the $4.97 shipping charge. That's $29 under the lowest price we could find for this quantity elsewhere. (For further comparison, we saw just one for $15 in October.) It measures approximately 9" x 25" x 35" and features two adjustable shelves.
