Free movie anyone? Use the code: FMN37 at any Blockbuster Express Kiosk and get a free one night movie rental! Expires 3/7/11 and can be used once per credit/debit card.
To find locations, and to see what movies are in the Kiosk, go here.
Also, if you get Redbox text message updates, you might have a unique code for a free rental today only. I did! Sign up here. I get a unique code at least once a month and not really any junk texts.
