I put a new 60D up on Amazon Marketplace. Got about 20 "hits", 19 of which were clearly scammers, 1 of which may or may not have been a scammer but by the time I got that one I was so sick of seeing junk emails from "buyers" that I just ignored it (that, and I had already sold the camera on Ebay)
I have to admit though, one of the scammers did an EXCELLENT job. Since it was the first one I got I didnt realize what was up.....said to contact them at a different email address (which I did, but also made sure to copy the Amazon marketplace address too). Then I got 3 emails: 1 from "Amazon Marketplace" saying it was sold, 1 from "PayPal" saying the money was in my account, and 1 more from "Amazon Marketplace" saying the item has been paid for and "now ship". If you saw these emails and werent really paying attention, you would have sent the item out....thats how realistic they were. Too bad for the scammer, an address in Nigeria always raises some questions. Logged into PayPal and hey look the money wasnt really there. And the item was still available on Amazon Marketplace.
So, everyone be careful out there, the seas are rough!
