As one of its daily deals, Woot offers the Pyrex 18-Piece Round Food Storage Set, model no. 1110141, for $19.99 plus $5 for shipping. That's tied with our January mention as the lowest total price we've seen. (It's also $16 under the best price we could find for a similar Pyrex set elsewhere.) It includes two 7-cup, two 4-cup, three 2-cup, and two 1-cup glass containers with BPA-free multicolor lids. Deal ends today.
