I've thought for a long while that the club should adopt a more competitive pricing policy for games like this for a while to see if it develops a habit for some extra fans
Other season ticket holders might moan as they pay up-front for a reasonable saving on an up-front price based on the standard ticket price, I'm not bothered by that. If you buy a ST then you get the certainty of your seat at a price you are happy to pay. Tickets that are hard to sell should be cheaper close to the day of the game and I don't think there will be that many people who would hold-off on buying in the hope of getting one of a few hundred cut-price deals
