Free Redbox Code

I just tried this code and it worked great!!!
Here's what I'm hearing, I haven't yet tried the code.
Right now you can get a free DVD rental at your local Redbox.
Simply use code: GANTS9. On the front screen, just hit rent with Promo code then type in the above code. This can be used once per debit/credit card, so you can rent more than one for free by using different cards! As soon as I try it I'll let you know if it works!
