Normally around $100-$140, so it's roughly half the full price.
Bloody Amazing Show, I just bought more tickets to watch it again.
There are good seats available, (I managed to snare some Gold Reserve Seats) from tomorrow to the 30th of November.
There are also $50 tickets available at the following URL if you want to sit in the Grand Circle. Kudos to Qwerty:

Maybe cheaper to spend the $$$ elsewhere
