Obviously short notice but HotUKers might be interested in this offer I received - I checked earlier and good £75 seats were coming up at £10. I'm sure they'll go pretty shortly!
On the 24th June last year Bon Jovi made history as the first band to open the O2. This week the band are back in London playing two stadium gigs at Twickenham. To help celebrate Making That Memory, AEG have allocated a number of best seats at £10 for this Saturday, 28th June.

EDIT: Sorry - I didn't mention the first part of the e-mail I got which said:
"GreenwichCard holders can snap up tickets for Bon Jovi at Twickenham for just £10 per ticket for Saturday 28 June. "
I suspect the Staff offer covers a wide variety of groups including the one above. No guarantees but I doubt you'd need the greenwich card to collect as ticketmaster don't ask for the number - besides you could just say someone gave them to you!
