Walmart offers the Pyrex 12-Piece Storage Plus Food Storage Set, model no. 1101605, for $16.88. Opt for in-store pickup to dodge the $4.97 shipping charge. That's tied with our mention two weeks ago and the lowest price we could find by $13. The set includes a 7-cup round container, 4-cup round container, two 2-cup round containers, and two 3-cup rectangular containers with lids.
