Overhead. No mailing costs. No printers to print tickets. No people running those printers. Etc. Right, I'm talking about printing tickets at home. Not printed tickets that get mailed out. I went to a Packer game in Miami a few years that probably had about 20,000 unsold tickets as that stadium is huge. Some friends who came to tailgate and hope for ticket bought $50 paper tickets from scalpers right before the game. Only one worked when they tried to go in but for whatever reason they let the other one through too, my guess is a decision was made with so many unsold seats to let people in to buy more concessions, etc. It was a mess, lots of people around our seats had tickets for the same seats. That was a weird situation but I have always thought the paper printed tickets was an issue because of scalpers. Pretty hard to stop it as long as you wanted to sell tickets online right up until the day of the game though. I tend to agree with whoever said above that the 10% of people who can't get it together in line now won't change that much with mobile device tickets. I don't really like the idea of buying concessions that way but it's just because I think things go quicker with cash, that may not be true anymore.
