Walmart offers the Rubbermaid 17-Cubic Foot Vertical Storage Shed, model no. FG374901OLVSS, for $149. Opt for Site-to-Store pickup to dodge the $99.97 shipping fee. (Amazon charges the same.) That's the lowest price we could find by $48, although we saw it for $30 less in May. It measures about 30" x 72" x 25" and features an impact-resistant floor and two doors.
