Redbox 10 Days of Deals
Redbox is offering up 10 Days of Deals starting on the 12th through May 22, 2012. Text the word DEALS to 727272 to get daily deals of .25 off to up to $1 off your next Redbox movie. You'll have to use the code they send that very day by the way and of course, if you don't have unlimited text then you'll be paying for the messages.
Looks like a few people have had issues with the text not coming through, you can check that out on the Redbox Facebook page. Looks like a good deal to me!
