Are there discounted day of show tickets at the box office?

They usually have a lottery

I Know if U Purchase At The Theater The Tix Are Cheaper Than Online, I Never Go To 1rst Day of Shows And I Always Get Great Seats @ Great Prices.

I don't know. You might get better results contacting the Cadillac Theater directly.

Some shows have day of show discount at the box office. Check online to see what's available day of, and pick up from box office when you arrive.
