Sorry for the late notice, but my son got his cast off today after having on for 6 weeks!
***UPDATE*** This code seems to be valid at select Kiosk locations only.
Today only, 8/21, you can grab up to 5 FREE Redbox Rentals with the code 12HHN756. You can reserve it online or get the movies right at the kiosk.
You will have to do a separate transaction for each movie you want.
