We know Redbox offers one of the best deals on DVD rentals, but isn’t FREE even better? When you text JOIN to 727272, they’ll send you a promo code for a FREE one-night DVD rental. As an added bonus, Redbox will send you a promo code for a FREE one-night rental every month. However, the freebie is only valid on the day that the code is sent, so you can’t save them up for a rainy day. Codes are sent randomly, and the day may vary each month. Remember, with text promos, your regular messaging/data rates apply, and you can always end your subscription by replying STOP.
