I still wish the club would do something like Watford do. My mate is a Watford season ticket holder who lives up north. But he has a special season ticket where he basically has 12 matches a year he can go to. And he just has to give the club a weeks' notice if he wants to attend one.
Not sure if it works out any cheaper for him, but it allows him to maintain that sense of belonging with the club.
And for me, I always say I'll drive up and get to a few home games every year but life gets in the way. Allowing me to buy something which forces me to sort my self out and get up for games would be a huge motivator to going.
Sounds a good scheme that for exiles.
