Tickets start at $49.50 for upper bowl seating, but right now there’s a Groupon for the concert that can get you a little closer for a similar price.
According to the Groupon website, the discount tickets to the Trans-Siberian Orchestra concert are selling fast, so you might not want to wait. On the other hand, Groupon does sometimes do percent-off sales with an extra 20% off local Groupons. (No telling whether this event will actually qualify for the extra discount.)
