My advice to anyone that purchases their tickets online, is that it's cheaper to purchase it at the venue. (This is for the local ppl. If you live out of state, then I understand why you're purchasing online)
Purchase your ticket(s) when the event is on sale. Then you won't have to pay the additional fees that come w/ purchasing tickets online.
SN:please don't purchase your ticket on the day of unless you just don't care where you sit.
