A best bet is the Sur La Table Square Bakers 3-Piece Set (pictured) for $39.99 plus $8.50 for shipping. That's $20 off list and the lowest total price we could find for this set. These porcelain bakers are dishwasher-, freezer-, microwave-, and oven-safe. Each measures 14" x 9.5", 10.5" x 7", and 6.5" x 5".
Of note, Sur La Table is also running a Holiday Sale and Clearance promotion, with discounts of up to 75% off. That's among the best offers we've seen on sale and clearance items from Sur La Table in recent months. (We last saw up to 80% off sale items and up to 65% off clearance items in October.)
