Where do you draw the line though?
Personally my line is about the £20 mark.
If I really want to go to a game I'll go, but speaking more generally, seeing killie away priced at £23 is over a line I've drawn, not because that extra £3 is going to break the bank, it's just too much for what's on offer in my eyes.
Given the likely standard of opposition and how early in the competition it is, I think £25 is pushing their luck slightly.
