I queued for about half an hour in the rain but it was totally worth it. I talked to the other people in the queue, sharing stories about what was worth going to and laughing as the man behind me told the guy advertising shows that ‘david schwimmer is a prick so i probably won’t like it’, and got tickets to exactly what i wanted to see at half price (US$50 a ticket instead of US$100 a ticket). They have an electronic board up that tells you which shows they are selling tickets for, how much the discount is, and what time they are on. Very useful! And it’s right in the middle of broadway/times square, so you can make it a part of your day there.
