Thought I'd share some Pyrex I found at thrift stores in Yuma, Arizona. Yuma is about an hour away and has some good thrift stores, unlike the small town I live in.
The Butterfly Gold fridgie was two dollars after discounts at the Goodwill, the plain mugs cost twenty-five cents each (I purchased three, only two are pictured, though) at the Humane Society Thrift Store, and the Woodland mugs were fifty cents each at the Salvation Army.
I was a bit bummed to not find anything in the colors/patterns I'm focused on collecting (basically anything turquoise, Butterprint or pink), but these pieces are so cute, too. I had never seen plain mugs and have no idea when they were made, but they go with everything.
