Well, the ticketmaster page says tickets will be shipped "at a later date." I thought someone posted in this thread that they'd be shipped closer to the event to avoid scalping.
Either way, I just don't understand the rush in wanting them mailed in three days. As long as they get to me before the 30th, I couldn't care less how long it takes. I guess if you need to get the ticket sent to someone else ASAP, I can understand, but I can't think of any other situations where it's that necessary.
