Home Depot offers the City Pickers Raised Garden Bed Kit in Terra Cotta, model no. 2340D, for $19.88. Opt for in-store pickup to dodge the $5 shipping fee. That's $10 under our mention from last May and the lowest price we've seen. (It's also a current low by $18.) It measures 24.5" x 20.5" and features an aeration screen, casters, water reservoir, and overflow hole.
