I absolutely love Redbox... new movies for only $1 per night!   There are over 27,000 Redbox Kiosks at McDonalds, Walmart, Walgreens, grocery stores, ...you name it.  It is very easy to use and if you are looking to try it for free, they are offering free codes to new and existing Redbox users.

For new users, click here for a free dvd rental 

Current users, be sure to sign up for the text alerts under your account settings!
Once a month and occasionally more, they will send out free codes!

Redbox also offers Blu-ray and video games which are $1.50-2.00 so the codes will discount by $1 off.
