Sam's Club offers its members the Rubbermaid 50-Piece Easy-Find Lid Food Storage Set in Red for $12.98 with free shipping. (Non-members pay $1.30 more.) That's the lowest price we could find by $12, although we saw it for $2 less during Black Friday week. This microwave-, freezer-, and dishwasher-safe set includes six 1/2-cup containers, six 1-1/4-cup containers, three 2-cup containers, four 3-cup containers, three 5-cup containers, two 7-cup containers, one 9-cup container, and 25 easy-find lids.
