That's student rush. I got first row for $62. It's half-price, whatever's left, 3 hours to curtain.
General rush is $30, and goes pretty early in the morning.
And the Hiptix are in advance but they only set aside a handful of seats per performance for that, and once they're gone, they're gone. It seems to have been selling well.
I'd say that if you want to see it, the student rush is pretty cheap and you can go to the box and get really great seats.
