Sometimes, if you turn up at the venue there are people selling excess tickets at face value on the night of the gig. Sometimes, people can't make it for one reason or another so ask their friends to sell the tickets on.
Just make sure that you know what the tickets look like and the security features of them. It's worth the chance and, if it doesn't work out, you've still had a weekend away.
Go on Jopsy, what's to lose and it's a safer bet than ebay. Us U2 fans HATE ebay, and so does the band and they refuse to sign stuff when they know it's for ebay. The sellers stick out like a sore thumb at events and us fans have been known to "remove" them from the venue
