This sounds like the guy from Nigeria who has $1 million in a US bank account and needs your help getting it wired to him . . . I have received this email about 7 times. I think I read about it in Newsweek last year too.
A new ploy for fraud?
I recently got an inquiry on one of my ads (not here on Audiogon but on another site) for a pair of interconnects. After a few emails back and forth, we agreed on the price of $90. The prospective buyer then said he is in England and would like to propose an (unusual!) payment method. He said someone in the states owes him $3000, so he will ask this guy to send me a check for $3000, I am to cash the check and then WIRE him the difference ($2910 in this case). Of course I said thanks but I deal in cash. I never heard from him again. Has anyone experienced this?
