I never noticed anything out of the ordinary through the course of the auction,and paypal'd him the money within 2 hours after it ended.
As far as I can see there is no justifiable reason for cancelling it,and I informed the seller of my opinion as soon as he approached me with this whole mess.
Still haven't heard from him,but looks like he's refunded my payment since my last post.. I'm sticking to my guns on this one!

Thanks for taking the time to help me out with this whole sorry affair,great work guys!

: From looking at the bids, it appears that no-one placed a single
: bid on the last day of the Auction, and they had plenty of time,
: as it didn't finish until 21h00.

: I agree with Jarl that this is a fair price- no certainty that
: re-listing would get him a higher price.

: If you would like to offer the seller an opportunity, I would let
: him know that if he can produce evidence within 3 days that the
: auction was seriously compromised, then you would consider what
: he shows you, but in the absence of that you expect the seller
: to complete his contract.
