Click “Connect With Facebook” button on this this Redbox page and you’ll get access to a promo code for a free Redbox rental valid 5/12 only. I already “Like” Redbox on Facebook, but to get the code, you’ll have to do it again.
With promos like these, I’d recommend getting to your Redbox location early in the day if you want the best selection. This is going to be a popular promotion!
