Was in the ticket office yesterday and asked them, They said they will be posted, if you don't get them, go to the ticket office on the day.
I've not got mine yet and am hoping the arrive as if there's a problem, there's going to be a long queue.
Not got mine yet.
Will be in the shop tomorrow on the way to my dear old mum's (gawd bless 'er) picking up a new shirt and will ask them if it hasn't arrived.
