I want to purchase tickets in the presale to guarantee that I can get them, it's pretty important to me that I go to this show. Anyway, I'm only 17 and would be purchasing tickets with my mother's credit card. She is not attending the show, so I was wondering, how can I go about picking these tickets up at will call? If this is not possible, do you think I will have any problem in the normal sale (ie, will the tickets sell out so fast I am unable to get one)?
