I think I've dropped a major bollock here!

It's my mates birthday that weekend so we've all booked up for a night out in Manchester and was going to get tickets for the fight. I've been looking everyday to see when the tickets become available and foound nothing.

Now my mate has just text to say all the cheap ones are sold out and only the £100 plus ones left (unless you pay extra for a shit seat tickets from one of the mark-up websites).

Gutted, what I thought would be a vheap night out is gonna cost a few bob mor. Any ideas on where to get cheaper tickets? Anyone know when they went on sale??
