Right now when you become a fan of Redbox on Facebook, you will be able to send a free one night rental code to a friend, redeemable May 13th only! Just click under the Mother’s Day tab to get started. This is a great way to throw in an extra Mother’s Day gift! After sending the Redbox code, you will have the option of entering your phone number and receiving your own code via text message. Enjoy sharing a free movie night and receiving one back next Sunday!
