No.
But nor has anyone else. The article on the Devils website says booking fee, but the actual website where you purchase tickets from doesn't. You are paying £2 to register for Cup Final tickets. If your team is successful, the £2 is deducted from your booking fee.
If you are struggling to understand, it's a bit like when Cardiff City were in the Premier League. For £30 (I think) you could join their membership club. Doing so wouldn't guarantee you a ticket for a game, but without it you definitely couldn't get a ticket.
I know you think you are trying to make yourself look clever but you are actually doing the exact opposite.
