Walmart offers the Rubbermaid Brilliance 10-Piece Food Storage Container Set for $19.98. Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with last week's mention and the lowest price we could find by $10. It features two 1.3-cup bowls, two 3.2-cup bowls, and one 9.6 cup bin, each with microwave-safe vented lids.
For in-store pickup only, Walmart offers the Rubbermaid Mini Ice Pack for $1. That's tied with our February mention and the lowest price we could find by $3. It's reusable and fits inside or snaps to the bottom of your container.
