I think season tickets represent excellent value overall at this club - however i also feel clubs could be much more innovative about how they make them accessible to more people. Back in the old days the terraces were where you could buy a cheap ticket - they were perfect for the local working class person. Unfortunately the loss of terraces in the British game has caused lots of issues for mondern day football, and I think the one of those problems is around make football affordable for all again.
If you look at someone like Arsenal, where ticket prices are utterly disgusting, the philosophy has changed. They don't have cheap tickets (like the old clock end) as they don't want the local lads from the Islington at the games, because all they do is buy their ticket, watch the game and go home. They want the tourist from Denmark who comes over, buys tickets for him and his mate/family, spends £100 in the club shop, buys a programme, food, drinks, etc spends £300 and goes home happy. Then next week a different tourist fan comes along and does the same.
Now i'm not saying we're like that, or that its even like that at every top flight club - But the gulf between the fans and football clubs is as big as its ever been, and that relationship has a massive influence on many things, including ticket prices.
