It's always best to buy away game tickets (and especially bowl tickets) through your school. The school gets a cut of the profits that way.

But, if you wait to buy them in Troy, they might be cheaper (like $15?). Troy has technically sold out only once (this year, against OSU), so plenty of tickets should be available. There does seem to be a good amount of interest in this games, despite the fact that Troy's last home game of the year is sometimes not well attended (usually because of Iron Bowl weekend and hunting season, but this year the Troy game date is later).

You can buy a general admission ticket at Troy and still sit in the FAU area (lower deck of the side opposite the press box). The visiting team sits on the north end of the stands nearest the scoreboard.

I hope to see a packed stadium and lots of FAU fans.
