Tupperware is too expensive. And you're absolutely right about how confusing they make it with all their different lines.

I have replaced all my old Tupperware with Lock & Lock containers. They are all freezer-safe. You can buy them in sets on QVC. You can also buy them at heritagemint.com. And I think some stores may carry them as well.

BTW, their regular line is not made from the controversial polycarbonate plastic that contains BPA. They do make a very limited line of polycarbonate containers, but they are clearly labeled as such. I just buy the regular polypropylene L&L. Great stuff.

Thanks suzyq3!! I'll give QVC a look.
