Purchase your tickets online. Your online purchase can be made on the show's website. You may also find tickets on an online ticket store, as some people sell their tickets online at the last minute if they are unable to go.
Purchase your tickets from the theater ticket booth. Theaters reserve an allotment of tickets to sell at the booth. You can also purchase cancellation tickets at this booth. Arrive early at the ticket booth, as these tickets sell out in a short amount of time.
Contact a ticket broker who specializes in Broadway shows. Brokers purchase a large number of tickets to popular shows and then resell them to the public. Be prepared to pay more for your tickets this way, as the broker must sell the ticket at a higher amount to make a profit.
Use cash to buy your tickets from a ticket scalper on the street outside the theater. You should only purchase tickets from a scalper as a last resort. You can purchase last-minute tickets from a scalper just before the show for a reduced price, as the scalper will be desperate to get rid of them. Look at the tickets carefully to make sure they are for the correct date.
