Paypal is open to abuse, you can issue a dispute and try and chargeback against paypal but that can only happen if there are funds in the accout to charge back against.
A common practice of the scammers is to give you a paypal account to pay to and then claim the good will take X days to arrive, when they dont turn up and you ask them about it they will say there is a delay but they have been shipped - this is just a ploy to lengthen the time from when the payment was made, Why ? so they can take out all the cash from the account associated with the paypal account and when you issue a dispute and paypal go to the account to charge back there is either no money or the account has been closed.
I guess they try to do this is batches to maximise the number of people they can scam in a given window and then harvest more cash.
