the problem is in this case I am not buying it. It is a laptop a friend is giving to me. So I am not sure how to address the value and there won't be any sales documentation.
Hmm, how best to put this? You show them a copy of the Paypal transfer order, you do not show them a copy of the message from paypal informing you that the payment has been rejected by the recipient and has been returned to your account.
