If you text the word WOW to 727272 Redbox will send you codes for discounts on movie rentals, games, etc over the course of 10 days (through 2/27/13) via text message. (Keep in mind normal text message charges/fees will apply.)
You can see all the details on the promotion and what discounts you might receive.
Thanks, Moms By Heart!
Mine for today was $.50 Off any rental and I have until 2/26/13 to use it. What did you get?
