You also want to make up some business cards to hand out to someone who buys your tickets, so they can easily contact you when they want tickets in the future.

Many times I've handed 2 tickets that were going to go unused to someone outside the stadium entrance along with my business card.  About 1/2 of those people have called me in the weeks after that game wanting to buy my season tickets for a future game.  Not a bad price to pay for gaining another person who wants to purchase my own season tickets.

If you don't let anyone know that you have season tickets, you will have a very hard time being able to recover some of your financial investment in your season tickets.
