Cheap broadway tickets?

i found a website called www.broadwaybox.com that had pretty good deals on broadway musicals, but is it a reliable source?? and it says that once i buy the tickets, i can use them whenever other than the blackout dates, but what if the day of the musical is sold out? can i still use them?

I agree about TKTS. Also, it's good to note that TKTS only gets tickets from shows that have empty seats available. You won't be able to get tickets to ANY show there. Shows such as Wicked sell out every performance and their tickets are NEVER available at TKTS.

broadway NY? perhaps musicals at north broadway (that is in the bronx)
dont do it... The only way i buy tickets other than at the box office is at the TKTS booths in times square and near the South Street Seaport. The tickets are sometimes up to 70% off face value and most of the time they are very good seats. One catch is its cash only and you need to get on line early to be sure you get the tickets to the show you want. its worth it
There is also a TKTS booth on 46th, near the Mariott hotel.
