I have been scanning eBay recently and have noticed that tickets for some venues, i.e. Manchester, Sheffield, Newcastle. Are actually going for less money than they where to buy in the first place, when you take the rip off bucking fee into consideration.
It is mainly limited to the standing tickets but thats the best place to be.
So if i where you and you still needed a ticket get on there and get them quick, they are bound to get more expensive nearer the date but at the moment they are good prices.
