When you refer friends to Redbox between now and March 17th, you can earn a FREE rental! You will sign up and be given a unique referral link. Then, when your friend reserves a movie on line (and pays for it), you will get a FREE rental!
Now, if they use a promo code to pay for it however, you won’t get one. The offer is also good for only one credit per referral – no matter how many movies or games they rent.
