That's not something to lie down and accept though imo. A season ticket at £500 a year is still affordable to a great deal of 'working class' people.
I'm hardly flash and going to an away game represents a small fortune to me tbh. Stoke away was £30 ticket (not that bad), £60 to get there from London, plus all the other cash you end up spending. I'm fucked off about paying £50 for Chelsea but will pay it because I live in London. If I was back in Newcastle it would put me off. It's only an extra 10-15 quid above what you've came to expect, but it's creeping up all the time man.
