No - if the cunning fan was going to every game they'd simply get an adult ST.So presumably:
Child season ticket + upgrade charge for every game < Adult ST?
Wouldn't the answer be to increase the price of the upgrade so if you upgraded every game you would still pay the equivalent of an adult ST? I must be missing something here.
Certainly don't want the club to lose any revenues but we are getting so many changes to conditions, rules & regulations that Barber will soon need to publish his very own Little Red Book!
But if they knew they'd only go to ( for example ) 12 games, then it maybe that a very cheap child ST + 12 upgrades is a cheaper way of going to those 12 games AND SITTING WITH THEIR CRONIES than buying an adult ST.
