I put my 2015 BTO 13" rMBP on Gumtree and someone has offered me the full asking price requesting that is is sent via Royal Mail /Parcel Force to a UK address in London and that the payment is to be made by PayPal. The person is buying it for a relative. As its a £1400 item I would rather face to face deal. What can I do to prevent being scammed? If someone sends the money to your PayPal account can I withdraw it immediatelly to prevent them from reversing the payment and making up some story such as it was not in the box or damaged etc? How do I know that they havn't hacked someone elses PayPal account? Is this simply too risky for a high value item? What are the typical scams?
