The Buyer actually wanted to pay via PayPal - but I forgot to add the Paypal Option on the auction- was too late once it had finished.
I gave the guy my paypal details - which he felt was dodgy as was separate to the ebay transaction.

I even offered to cancel the auction and relist with a buy now at the winning bid with the correct payment options.

instead the buyer changed his mind then left me Neg Feedback claiming I was trying to complete the transaction out of ebay!
