i'd mail him, if you haven't already. And then ebay.
This is the second time ive seen the knob on sale from him. The first time it sold for about 51 quid. And then within the next 5 minutes it was relisted (when you won it)
I did mail him to ask why it had been instantly relisted and he replied (quote):
"Some idiot bidded then messaged me 5 mins before end to cancel I left it as didn't read it in time! Annoying"
I'm always wary of shill bidding, and this to me seemed a prime example. Maybe he just didn't get what he wanted for it, again. As I said before, paypal to bank transfers should now be instant. But even when it never used to be, it would only take 5 days.,.....
Then again, I could be wrong....
