Glass tupperware for $20

Microwaving in plastic? You should probably stop that.
Studies seem to conflict and I'm not really sure whether it's truly bad for you or not, but why not switch to glass to be safe?

Especially when you can get a set for under $20.
This is very tempting and I am going to have to bargain with E to see if he will let me swap out some of our plastic containers and buy these. They take up more room, and are more expensive, but they are hopefully longer lasting and better for us and the environment.
