Walmart offers the Rubbermaid 8-Piece Dry Food Container Set, model no. 1776474, for $15.97. (Amazon charges the same for Prime members only.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our mention from December and the lowest price we could find by $15. It includes 1.2-, 2.4-, 3.8-, and 5-liter containers with corresponding lids.
