Walmart offers the Mainstays Leaning Ladder 5-Shelf Bookcase in Espresso, model no. MS12-021-006-02, for $45. Opt for in-store pickup to avoid the $5.97 shipping charge. (You can also pad your order to over $50 for free shipping.) That's the lowest price we could find by $19, although we saw it for $5 less in May. It has five shelves, each capable of holding up to 45 lbs.
