Prices are usually pretty set. They offer Annual passholder and Florida resident discounts sometimes, just ask when you call the box office. I see your from West Palm. I believe they are running a Florida resident rate right now (half off select seats)... You would have to call the box office to ask. The shows usually sell pretty well, so discounts (if there are any) are in the slower season.
