Not sure if they sell GA season tickets for non-students. I know when I first bought mine back in 1990 they did not but then reserved seating season tickets were so cheap (40 bucks I believe, less than a dollar a game) it didn't matter.
As much as I see you posting I am shocked that you need to ask. 2014 reserved season tickets were $350 plus $90 parking. Just got basketball renewal wit $500 seat donation; parking $100, and tickets $325. Throw in football it gets juicy!!
