Yes, if, for instance, you picked the $240 (I think it is) level and you want 3 seats, that'll cost you $720 just for the donation. Then, you will also have to buy the season ticket package, which is "around" $280 per seat. So, $840 + $720 = $1560.
But I hear the waiting list is insane. Lucky for me, I got my season tickets when we sucked! haha
