Also once had a bloke win a mobile I had on there...he then said that he couldnt pay it for 2 weeks because he was short of cash, but it was for a friends birthday so could I send it now (NOT to the address linked to his account) and he would pay for it when he had the money. Lets just say that never happened!
But then tbf, there are some good people on there. I won a tshirt on the tuesday, emailed the guy to say I'd send a cheque (before the days of paypal) on the Friday and the tshirt had arrived in the post by Thursday! Still sent the cheque of course
