Today only, you can score a FREE 1-day DVD rental (or get $1.20 off a game or Blu-ray rental) when you enter the promo code 12HHN756 valid at Redbox.com, on the Redbox Mobile app, and your local Redbox kiosk.
If that code doesn’t work for you, you can also try this code: 22hhn756 to see if it works for you.
UPDATE: I’m getting reports the first code is only working for about half of you. It seems like it may be select kiosks only. So be sure to check online to see if it works before heading to your local kiosk.
