I love renting from Redbox and I’m really excited about their refer-a-friend program. When you refer-a-friend through this promotion, you get a credit for a free Redbox rental. The friend will need to be a new Redbox customer and create an account through your link for you to earn credit. Once your friend rents a movie online, they will receive a free movie rental too. Click this Redbox link to get started (this is my personal link).
