I saw them in various colors tonight when in Target, but don't need any.
My mom had several pieces, such as cake and pie carriers, pitcher, measuring cup, and a couple bowls. I think the pie carrier is the only thing I have left. I noticed after a few years that the plastic started to feel sticky, and then become brittle. The measuring cup actually cracked and leaked.
I really prefer to store foods in glass or stainless steel containers, or alternately hard plastic. I have a couple Cambro polycarbonate containers, and just bought a 1 qt. one for my sister's Christmas gift. They don't seem to be any more expensive than Tupperware.
