I would be willing to bet that a lot of those listings are fraudulent anyway. I bought over £500 worth of tickets from eBay for Twickers night 1 after they sold out through Ticketmaster but both of the sellers I used ended up scamming me out of my cash.

No tickets, no refund, zippo care from eBay, Paypal or the local police and I'll never buy tickets through eBay EVER again.

I ended up having to pay £170 for just two replacement tickets from Ticketmaster who'd decided to release some more after I'd already been screwed just so I got to see the show and wasn't left feeling as bitter as I might otherwise have been.

This problem will always exist unless eBay changes it's policies to allow decent and honest buyers to bid as much as they like for tickets without having to complete payment in order to drive the touts out of business. If people have to sell tickets on eBay for genuine reasons, they could use 'Buy It Now' auctions at face value.
