Walmart again offers the Plano 4-Tier Heavy-Duty Plastic Shelving Unit in White, model no. 917700, for $14.97. Choose in-store pickup to avoid the $5.99 shipping charge. That's tied with our mention from December and at least $5 less than you'd spend at another local retail store. It measures 14.25" x 22" x 48.25" and features tool-free assembly.
