Walmart offers the Rubbermaid Easy Find 28-Piece Food Storage Set, model no. 1792658, for $10.97 with free shipping. That's tied with our mention from a month ago (which required pickup) and the lowest total price we could find by $5. It includes eight 1/2-cup containers, four 1-1/4-cup containers, four 2-cup containers, four 3-cup containers, four 5-cup containers, and four 7-cup containers. All of the containers feature lids that snap to each other and to the bases of the containers.
