Today only, Monday Nov. 18, you can get a free Redbox movie or video game rental by using promo code REDBOX17. The code should work online, in the app, or at the kiosk. You'll only get the first night free, so don't keep it for longer unless you want to pay for a second night.
I suggest using the code online and reserving your movie ahead of time! That way you won't be the person at the front of the line taking 30 minutes to pick a movie. Some of us have things to do. Like making fun of people at the front of the line taking 30 freaking minutes to pick a freaking movie!
