This is a common eBay scam on pinballs as well, now being high value collectables.
Emailing unsuccesful bidders on other auctions with the too tempting deal. Payment by Western Union which is non-charge back able.
Item is always , NIB something nice, and in another country but he can do you cheap shipping.
Scammers may used hijacked accounts as well, one day they have 500 feedback doing Cabbage Patch Dolls in Missouri, next they have 6 NIB Addams Family`s in Marseille that they need $1500 a piece on.....
If its too good to be true......
