Walmart offers the Pyrex 12-Piece Storage Plus Food Storage Set, model no. 1101605, for $18.84. Opt for in-store pickup to dodge the $5.97 shipping charge. That's tied with our mention from July (although that deal included free shipping) and the lowest price we could find by $12. The set includes a 7-cup round container, 4-cup round container, two 2-cup round containers, and two 3-cup rectangular containers, all with lids.
