A true story...
Got an email from a scammer. Said he wanted to buy my "product," wanted to pay by credit card, and wanted it shipped by DHL to Nigeria.
I had nothing for sale, so I asked to which product he was referring. He responded by asking for my web site so he could see what I had for sale!
Deciding to end the transaction at this point, I responded that my web site was www.sony.com, as I knew he would wise up at that response. In his next email, he actually asked for 5 ea. of several items, and asked for the total due.
Fun, fun, fun!
