Tickets and discounts
We recommend using the following for obtaining tickets:
Beware discount sites and scalpers. You can always go to the box office for theatres in person, or call the theatre directly for tickets. A list of all Broadway theatres, with contact information and Google maps, is available here.
Each Broadway theatre has its own rush policies, lotteries, student/group discounts and promotions for musicals.
You can find a good list of all of those for current productions here.
