Walmart offers the Rubbermaid 40-Piece Food Storage Set, model no. 1913801, for $9.89. (Target charges the same with in-store pickup.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from last October, $3 off list, and the lowest price we could find. It includes four mini containers, four mini deep square containers, three square containers, four small bowls, two deep square containers, two twist and seal containers, and a storage tote.
