I've not found a buyer through ebay for free though. Whatever happens, ebay have had £5 out of me for listing fees on the auctions in the 1st place. Thats more than enough in my opinion. I don't want to give £20 on top of that.
I've got a feeling he will want to go through ebay to buy the goods, some people prefer the 'saftey' of it. I'll ask him on a bank transfer though.
