Nothing can be dinne through eBay now .
The buyer can repay you through a PayPal Friends and Family Payment, or you can send them a PayPal invoice. Or they can repay with a cheque or bank transfer which ever suits you both best.
With PayPal payments email addresses are required for this, be very sure, and very clear in your eBay messages the reason for requesting an email address, that it clearly shows it is not for an ' off eBay sale'.
