The biggest provider of half-price and other discounted tickets in Massachusetts is ARTS/Boston which is still going strong several decades after I helped create this umbrella organizaion. They have two BOSTIX booths with day of performance half-price tickets. Their half price kiosks are located in Faneuil Hall Marketplace and Copley Square. There are also advance on-line discount tickets, and you can find all the details on their website. Bostix has more than 160 participating arts organizations and theatres.
