Don't forget that you can get a free movie code texted to you once a month on a Monday from Redbox. You can reserve your movies for $1 on their website and return them to any box. I love Red Box! If you become a fan on Facebook they give you a code too. You can use codes when you are at the box, not reserving online and they are per credit card use.
Currently you can use these codes any where - BREAKROOM and DVDONME
This one is only good at Walgreen locations - DVDATWAG
This one is only good at McDonalds - N3WY3AR
