it's bonkers. you'd think the market forces (supply and demand) would dictate that the initlal prices would be raised significantly, yet the Rolling Stones and Madonna both charged about �150 for recent gigs (to much outcry) and STILL people paid this happily and STILL people paid hugely inflated prices on eBay once the official lines had sold out.
it's like going to these gigs has now become a status cachet - a 'been there done that' type thing rather than an actual event for enjoyment for some people.
I agree that they're probably going to have to put some sort of Glasto-type registration system in place to stop this. But then again, if going to a gig is worth �200+ to some people, who are we to stop them paying that? That's a free market for you!
When people buys shares in a company, it's because they think that they will be able to sell them at an increased value...they think they're getting a cheap deal. The eBay sellers who buy gig tickets are no different.
You've got to wonder why the artists, promoters and record companies are undervaluing their tickets so much? It was the most predictable thing in the world that these gigs would sell faster than you can say 'have another espresso Robbie'
