There is a Redbox code available today for a free rental.
Redbox posted this as a Buy One Get One Free code but I just tested it online and it worked for one movie completely free for me.
I would strongly suggest trying the code online at the Redbox you prefer before you head out just to be sure it works for you. Sometimes these codes will not work at certain locations etc…
So anyway- head over to Redbox today only (Thursday) and use code: MARCH27 and see what you get.
I selected a random DVD and my total was $0. If you do reserve online the movie will be waiting for you at your selected location.
