Here's a code for a free Redbox movie rental valid today, 11/23!
Add a movie to your cart online at Redbox.com. Use the code 8MA574WW at checkout to get it for free!
Once you rent the movie through their website, you then go to the Redbox kiosk to pick it up. You will need to swipe the same credit card that you have registered with them online when you get to the kiosk so they know which movies to retrieve. You won't be charged for them unless you return them late.
Thanks to Freebieshark.com for the code!
