Walmart offers the Rubbermaid Brilliance 10-Piece Food Storage Container Set for $16.98. Opt for in-store pickup to dodge the $5.99 shipping charge. (Amazon and Target charge the same price via free shipping and pickup, respectively.) That's $3 under our April mention and the lowest price we could find by $6. It features two 1.3-cup bowls, two 3.2-cup bowls, and one 9.6 cup bin, each with microwave-safe vented lids.
