Oh how I love Tupperware! Not available in stores, but you can get it online, and you can also get cool vintage Tupperware on ebay.
What I would really love to find are two Tupperware toys that I had when I was a kid. One was a juice set, with a mini pitcher like the one above, and four little cups (in 70's yellow, orange, brown, and green). The whole thing was housed in a rectangular container (I think it was brown) with a clear lid, and I think there were a few other things in it. The other thing was a baking set for kids, with a pastry mat, rolling pin, etc. Tupperware, if you're reading this, please bring these back!
