Text the word SHOPS to 727272 to get a code for a FREE one-night Redbox DVD rental. This one time use code will be valid for a week after you receive it.
I have not tried it at a kiosk, so be aware this code may not work at the kiosks. I’d recommend using it online to reserve your free rental.
If you try it at the kiosk, let me know if it works for you.
