For those who have a Blockbuster Express Kiosk you can use the code: GW12B1 to rent one movie and get one FREE!  Blockbuster Express kiosks can be found in many Publix stores. Go HERE to check for a kiosk  in your area. This code expires 2/8/10. This code can be used once per debit/credit card.
I can’t guarantee the code will work but the email gave me the option to share with a friend…so I am thinking the code should be valid for others too.
