Made me laugh, I let eBay know and they pulled it straight away, then they sent me an e-mail thanking them for the amount of dodgy auctions I've alerted them to recently. Perhaps I ought to suggest they pay me?
In all seriousness, if some lowlife scum e-mails you with an offer like that, shop them straight to eBay so that someone less intelligent than you doesn't loose a serious amount of money!
