Walmart offers the Pyrex 14-Piece Glass Round Storage Set, model no. 6022369, for $14.97. Choose Site-to-Store pickup to avoid the $4.97 shipping fee. That's tied with our mention from three weeks ago as the lowest price we've seen. (It's a current low by $12.) This dishwasher-safe, non-porous glass set includes four 2-cup rounds, two 4-cup rounds, one 7-cup round, and seven blue plastic storage covers.
