You can still buy now. Available for £2500 including this game and FA Cup Semi and final. Plus all the England shite and you can flog back tickets you don’t use for those games. Says nine games in total. Includes train travel to games and airport lounge access (for some reason).
There is no face value for this game as you can’t buy for this game alone.
What is weird is who buys these games when someone sells them back to Wembley.
I've touched lucky that a mate of a mate bought one a while back (not a red) and rather than send them back to Club Wembley he's said I can go.
But like you said, not available to buy as a one off, so who exactly are Club Wembley selling them to?
