We ordered from Ticketmania for our trip last month. They sent the actual tickets, with a photocopy of the front and back of each ticket (something I always do myself), by an overnight delivery service. I had them send them to my office so my assistant would get them instead of having them delivered to my empty house. If you order far enough in advance, they send you an e-mail telling you when the tickets will go out so you can watch for them. I don't know what your timing is like, but I liked getting them before we left for our trip.
Have fun.
