I am planning on just entering the concert using my credit card, but I always like to have a backup. I logged on to Ticketmaster to add the tickets into my passbook app on my iPhone. When I did this I noticed that I had the option to actually print one pair of tickets at home, however the second pair of tickets says "paperless only" and had no option to print them. Just wondering why I can print one set, but not the other?? THe only reason we bought two pairs, is because we couldn't get 4 seats together. Any ideas???
