Here is a new code to get a free rental at Blockbuster Express. (I used the code tonight so it worked for me!)
Here is the code: 14CHD2X
This is good through January 20th. Remember, that you have to return the movie by 9 pm the next day or you will be charged for a 2nd night.
You can go here to locate a kiosk near you.
Thanks, My Frugal Adventures!
