There is a super shady thrift store that I like to frequent. They have good prices and you have to dig, but I usually can find at least one skirt or dress that's in good condition, fits, and is super cheap. But they hardly EVER have decent housewares. I always check (just to be sure) but so far I've come up empty handed on the Pyrex side of life. However, my mom must just have better Pyrex luck than me. She brought this baby home for $1.50. It's in great condition on the outside but a little bit the worse for wear on the inside... but for $1.50, who cares? :)
You can't really tell from the picture, but it's a 404.
