I believe that most of the discounts were pulled after opening night, although it seems that they are coming back. There is a "new" one at BroadwayBox, but only for 20% off.
A show like this needs to rely on word of mouth to get people in the door. I don't understand the principle behind limiting the discounts relatively early in the run. If you can't get people in the door, there's no one to give the word of mouth. Several struggling shows have tried pulling discounts to beef up the box office numbers, but I'm having trouble thinking of a time when that strategy worked for a struggling show.
