I am finding the same issues here In Canada with Canuck Audio Mart, and Kijiji. It seems to be getting worse every day. Just this morning I had a lowball offer of half my asking price on an item. I used to get pissed off, but now I just accept it for what it is, and ignore the person completely.
@d2girls I do not know of any other site, besides CAM, here in the Great White North either.
