Walmart offers the Chef Buddy 54-Piece Food Storage Container Set for $7.11. Choose in-store pickup to drop it to $6.59. That's tied with our mention from a week ago and the lowest price we could find by a buck, outside of the mention below. It includes 27 microwave- and freezer-safe containers with matching air tight lids.

A close price: Amazon offers it for the same price with orders of $25 or more.
