OP, as a 46-year season ticket holder, I do not recall any giveaways or anything special for season ticket holders. I will qualify my statement by saying, I am not a big donor or have premium seats so maybe those persons are offered things I am unaware. The only benefit I have seen is the ability to have access to away game tickets, bowl games, and closer-in parking. But even so, the number of seats or the location of parking is based upon your Volunteer Athletic Scholarship Fund ranking.
Glad you are a new season ticket holder and GBO!
