I find the occasional tupperware now and then, but mostly with missing lids and not in very nice condition. But when I do find them in nice condition, I do grab them.
Very good condition.... Jelly mold with Christmas theme, but with no lid. Never mind, it can still be used of course;
Very good condition... Flat container without lid, and harder to use of course. However, I could use it as a nut or candy server if I get desperate enough;
But on one occasion just recently, I found one WITH the lid and in beautiful condition! She's a good size at around 13 inches long;
