Update: The Domino's promotion I mentioned earlier today (see below) had some major issues. When the giveaway went live, their site crashed, and it seems that no one received their pizzas. If you shoot customer service a quick e-mail, they should respond shortly with a promo code for a free pizza. Just mention that you tried the promo, reached the final submission page, but it never loaded with the code. Good luck!
Keep 'em coming, Blockbuster!
These codes for free $1 rentals are good through 9/23. As always, bring the entire list with you when renting - not all codes will work.
Add to that a free pizza from Domino's, and you've got yourself a nice night in!
