Last year a lady in TN was "selling" speaker cables at a very good price. I bit, even though she had no feedback. She had a nice voice over the phone when I talked to her at her place of employment- a bank. I sent a money order for $600. After a couple of days, the ad had not changed to sold, or pending (hint to all scammers). So I called her again. This time she was rude and had no time to talk because she was at work, etc. Another call was even more rude and short. Then someone posted a scam warning beside the ad (thanks to the member who took the time to warn me/us). Anyway, I got in touch with the other member and he gave me her home phone # which I called, now the weekend. She was more rude and angry, I won't say low class because it would it would be an insult to low class. On Monday, I called the bank and spoke to the manager, he asked me to explain. Then he said that she called him at home the day before, Sunday, to resign from the bank. No explanations from her. He intercepted my letter which contained the money order and returned it to me. I got 3 emails from members who had been scammed by this same person. The only ones who got their money back, to my knowledge, were myself and the guy who posted the warning.
In the past year I have made it a policy of mine to request that seller send me the item, or one piece (one speaker, for instance), then I send some of the money, to be paid in full only when I get what I've paid for. I do this if the person has no or few feedback. This has worked well. Most of the time the deal falls through, the seller somewhat pissed that I would make such an outrageous request- I understand. But, if you can't trust me, then who can you trust, IMHO?
Have fun and be careful!
P.S. I've noticed an increase of shady audio "deals" coming out of the U.K., especially on eBay.
