Right now you can get a FREE one night rental code for Redbox when you download the FREE Redbox App and then text RBPLAY to 727272. You’ll receive a text back with a code for a FREE rental (one time use; can’t be shared).
For Android, just search “redbox” in the play store. For Apple products, go here.
You will need to use the code with the Redbox App. To use your code, just reserve a movie using the app and at checkout, click on “use credit or promo code”. According to the fine print in the text you may also be able to use the code online as it says ”valid in app or online only, not valid at kiosk”
