How do you pre purchase parking?

To get pre purchase parking at Banc of america stadium i think you have to purchase season ticket. I live 1 block from the stadium i have parking space available for the LaFc.LaRams.UscFootball games less cheaper than at Banc of america stadium...

Helpful tip we learned: get $6 indoor parking near 9th Street and Flower, then take the Metro Expo line to USC/Expo Park. Great crowd and less traffic.
