Not all games for flexi season tickets are priced the same equal amount.
It appears as though some flexi season tickets will continue to pay a different amount per game, depending on the opposition and which category the game is.
Although this would seem to be dependent entirely on where the season ticket is located and whether or not it is a junior/concessionary.
I have two flexi season tickets in my family and for one the individual games are calculated the same throughout the season and for the other it is calculated depending on the category/opposition.
They are both in different parts of the stadium and one is a junior.
