Kmart offers the Rubbermaid 40-Piece TakeAlongs Food Storage Set, model no. 1949248, for $9.99. Opt for in-store pickup to avoid the $5.99 shipping fee. That's the lowest price we could find by $8, outside the offers below. This dishwasher-, freezer-, and microwave-safe set features ridged lids for more stable stacking.
A couple close prices: Amazon and Target offer it for $10.99 via Prime shipping and in-store pickup, respectively.
Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
