So I'm taking classes at UCB and was given the red i.d. card to attend shows. My question is in order to utilize the discount associated with the card, is my only option to show up before the show and purchase tickets then? In other words, is it correct that I can't get tickets in advance (online) and receive the student discount? Some of the shows are very popular, especially on weekends, so purchasing in advance I would think usually would be better to guarantee entrance.
