Who's pre ordering it & who's buying it on the day? Anyone worried they'll lose it. Just placed my order to get it from the stadium.
If anyone is worried about losing them or them getting damaged and is stopping over in London on the night of the game, I'd set off early and go to Wembley and buy them on the way to my hotel. (although I'm guessing with the marathon the traffic might put a few people off, if you're on train a day travelcard for the tube so you can nip in and out of Wembley might be worthwhile) For the Playoff Final I was stopping next to Wembley. I had my breakfast and then went straight out to take some pictures of the ground before the place got too busy (plus I wanted to go to the pub at lunchtime and then straight down and into the ground). The shop at the ground was open at that point so I bought my programme and scarf (just our colours, but a PO Final special) and then took them and left them in my hotel for the rest of the day. Can't see why the shop wouldn't be open in the same way this time round.
Yeah, I've remembered now you've said that. They're due in on Friday afternoon so you can always go and buy one on Saturday.
