Tickets, you mean? You have to print them (unless I missed that there was an option to have them mailed). In the email from Ticketmaster, there's a link that says "Print my tickets". I don't know whether you could also bring up the tickets on a smartphone... anyone know if they allow that?
I have not yet received my tickets through May 26. The SAVOR site indicates that they will be mailed out on Ticketmaster on May 21. If they don't arrive on Tuesday I will be a bit worried.
