Walmart offers the Chef Buddy 54-Piece Food Storage Container Set with Air Tight Lids, model no. 82-54PSS, for $11.97. Opt for in-store pickup to avoid the $4.97 shipping fee. (Home Depot has it for a few cents more via pickup, while Amazon has it for the same price with free shipping for Prime members.) That's the lowest price we could find by $3. It features 27 microwave-safe containers with matching lids.
