Redbox is offering a free-bee movie rental code when you “like” them on Facebook. If you already “liked” Redbox, there should be a code waiting there for you! Click here to pick up your free rental. Sneaky inside tip: I have noticed that codes work once per credit card, meaning…if you use more than one card, you’ve got more than one movie! Just be sure to return them within the 24 hour free-bee period to avoid late charges.
