Just been reading on MEN about how they think we will pay fortunes to touts to get tickets into the game. This is caused with the allocation for Club Wembley & the FA Family.
If anyone does buy a ticket on the black market, you should write a letter of complaint to the FA after the game, enclosing your stub as proof. They can track every ticket and should then identify where the ticket originated from and deal with the original seller accordingly.
Not much recourse, but it may get the guilty party blacklisted and who knows if enough are sent in result in these sources allocations being reduced
