There is a new FREE Blockbuster Express rental code available until 2/3/11: 28CHD4X
And don't forget about this code expiring soon:
MRC37H Exp. 2/25/11
Movies are due by 9 PM the next day to avoid the $1 nightly fee. A little trick my hubby and I use is to use the same code twice by using both of our debit cards. The codes can be used once per card.
You can find a Blockbuster Kiosk near you here. You can even reserve your movie online.
