Whay can't you just buy them normally? My partner won ours at at party in February...no tickets yet so I guess we'll have to chase this one up. Tickets went on sale 27th April....have they run out already?
The prices are falling on ebay. Someone got one for under Â£100 recently. I reckon there'll still be some being sold a couple of weeks before the event, and they should go pretty cheaply.
Just keep checking back.
In the unlikley event anyone is trying to get rid of any unwanted tix - I've got some slack mates who never quite got around to getting them when they came out & are now cursing themselves.. They are willing to cross palms with silver for tickets - so PM me if you have one (or even better two) spare.
