Lol, Camera, I looked at the list and found suitable canidates for each..right here in the forum!!
Wish I could help you out with the worst buy, but I honestly do not buy very much and what I do buy, has been researched fairly carefully....ok. ok. so I bought a paperweight that had a flea in the middle of the glass. They wanted me to return it and pay shipping. Well that's not cheap for a glass paperweight. I ended up giving it to my granddaughter.
