I'm posting this because I saw a scam post on qrz.com about this person, and it (almost) happened to me.
I posted a "want to buy" ad, and received a very simple reply that "she" had one for sale. I asked for a picture and price. She sent a picture with no ID (QSL card, piece of paper with call sign, etc) and a ridiculous price...same as retail. I countered with a low ball offer and she accepted. She claimed to have purchased it one month earlier from DXE, so I then asked for a new picture with a copy of the DXE invoice next to the item. No further response. Really strange, in the back of my mind, I seemed to remember the same picture with no ID from another person's ad for the same item, but couldn't go back and find it. Probably copied that picture and sent it to me. Beware....
