Through the Playbill club, Roundabout is offering a very nice selection of orchestra and front mezzanine seats for 99 dollars until the end of the run.
The usual suspects are present. It doesn't apply to the last weekend and on weekends the cheap seats don't kick in until about row G or H of the side orchestra. On less popular days the discount might start in side orchestra row E or F. If you're willing to take the seats right next to the wall, and there really isn't any obstruction, even for popular days you are good.
Saturday, July 4th, maybe because it is the holiday, has a lot of bargains. Side orchestra seats closer to the aisle than the wall starting around rows G and H.
And plenty of 99 dollar front mezzanine seats available.
I have tickets for the last performance on Sunday, July 19th in center orchestra Row H. Should be a lot of fun. There's a nice pair of side orchestra Row H available at this moment. Seats 12 and 14. Sorry, but they're full price.
