They started sending them out on Monday the 22nd. You should get tracking info when they are shipped out (if your email address is correct in the system). If you haven't gotten them by next week, I'd call the CoTA office.
When I hadn't received mine by Wednesday the 24th and all of the other people in my group had already gotten them I had a minor panic attack and called my contact at CoTA.
He said if they're not there by the end of next week to call back. Sure enough, on Thursday I received tracking info and received the tickets this Monday.
Since they have to print out and ship 120,000+ I think it's taking them a while. They ship out of Arkansas, 2-day FedEx. Parking passes should come with the tix.
Hope they arrive soon!
