There is a Redbox code available for a free movie rental today only. This works for the DVDs and if you want a Bluray you will need to pay $.30 or so.
You can use coupon code: DWTFREE4 for today only (2/6) to get your free rental.
With these codes, I always recommend reserving your movie online so you can be certain the code works for you. I just reserved Flight and it worked perfectly.
And if tonight you are busy having a life and you aren’t laying around sniffling and coughing and feeling miserable like me, you can rent a free movie another time when you download the Redbox app.
