I advertised a motorbike on Gumtree and have been contacted via email by a keen buyer. He says that he can only pay via PayPal and will pay all associated PayPal costs. He wants to pay ASAP and will have someone collect the bike because he is away...out of town. Of course I would not allow anyone to collect the bike unless I was 110% sure that payment had been received but I'm not so sure about PayPal fraud? It all sounds a bit suss to me?
