I gave up my season ticket 4 years a go. It was around £380 then, and went to £425. It is currently around £700 i believe. It wasn't just the season ticket price. Parking went from £5 to £10 over night. The beer and food also went up. At the time, i couldn't justify the extra expense, so decided to use that seasons ticket money to nail the biggest moveable satellite dish to the side of my house. I now watch every City game that is shown somewhere in the world.
I still get the odd ticket, but it is never in the same place.
My finances are now on the up and i could justify getting a premium seat. But i really enjoyed the standing section, as i just cannot sing sat down. I cannot imagine i would get away with standing in the posh seats!
I've also got out of the habit of going. I used to have a routine, and couldn't wait until the next match. Now i just plan what time to turn the TV on and watch.
I don't blame the club for price rises (it's a business). I just decided for my self that i wouldn't pay it. Not bitter, just smart...
