Amazon offers Prime members the Rubbermaid Brilliance 10-Piece Food Storage Container Set for $11.39 with free shipping. (Target charges the same with in-store pickup.) That's $1 under last week's mention and the lowest price we've seen. (It's a current low by $1.) It features two 1.3-cup bowls, two 3.2-cup bowls, and one 9.6 cup bin, each with microwave-safe vented lids.

Update: The price has increased at Amazon; however, Target still offers it for $11.39 with in-store pickup.
