Athletics has got to sell season tickets for the prime seats. I think that any school that allowed single game purchases of seats for prime games would lose a lot of revenue. I can't imagine that's available hardly anywhere given revenue needs.
How?
This year, season ticket prices for a Silver seat totals to $215, Gold at $300, Platinum at $430. Divide those numbers by 17 (# of home games including the Indiana Tech exhibition) and you get $12.65 per game for Silver, $17.65 for Gold, and $25.30 for Platinum.
I don't know if athletics charged less for other single home games in the upper deck, but tickets for Saturday's Buffalo game are going for $20. Assuming all single game seats were $20 this year, I think athletics could charge $25-$30 for a single game Silver seat, $30-$40 for Gold, and $40-$50 for Platinum. It would make the premium tickets available to non-season ticket holders who can afford them (think out-of-towners, like me) while still making season tickets a hell of a good deal. If you charged $35 for a single game gold seat, that comes out to $595 for 17 games. A season ticket holder would get a $595 value for $300!
