Walmart offers the Rubbermaid 8-Piece Dry Food Container Set, model no. 1776474, for $15.97. Opt for in-store pickup to dodge the $4.97 shipping fee. (Amazon charges the same with free shipping for Prime members, albeit with a 3-to-5 week shipping delay.) That's the lowest price we could find by $9. It includes 1.2-, 2.4-, 3.8-, and 5-liter containers with corresponding lids.
