Walmart offers the Plano 4-Shelf Storage Unit in Light Taupe, model no. 907, for $14.71. Opt for in-store pickup to avoid the $4.97 shipping free. That's tied with our mention from last week, since expired, and the lowest price we've seen. (It's a current low by $22.) This shelving system is made from heavy-duty plastic and features snap-lock assembly.
