I have a membership and can't decide whether to buy a ticket before general sale or wait till general sale opens. I bought a ticket for the Vitesse game on the opening day of the ticket office, and due to the fact that the season ticket seats were already reserved the actual seats available to purchase as a member were very limited. When they went on general sale, and I assume after lots of season ticket holders didn't purchase their seat, there was a lot more choice of where to sit in the stadium.
So whilst the membership might enable to purchase the seats before they go on general sale, it is kind of stupid, because there are very few to pick from.
I am two minds whether to purchase now or not.
I assume this game might be more desirable than the Vitesse one, so maybe there will be more ST holders buyimg their own seat?!
