Hi, Redbox is offering a FREE game rental from Redbox.com. Use this soon as it can end at any time, but I believe it is good through October 4, 2015.
Use the code NEWGEN and you will get a free game rental.
Click on my Free Stuff page at the top of this page, because I have numerous codes listed for a free one day movie DVD from Redbox. You could use one of those too, if you haven't already.
