Watch Fandango's facebook page, cause sometime today they're gonna post a code for a limited number of tickets.
Yesterday it was 500. Don't know if today will be the same.
Select the movie, theater & showtime you want. Enter a minimum of 2 tickets for the same movie & check the box to indicate you have a promo code.
These are going to go really fast so you gotta be quick if you want to see that movie
