Actually, the VISA discounts have been extended through 12/31/2012. Yes, that's 2012 for both
Alamo and National. Unfortunately, it still says 10/31/11. Click on it anyway, and when you choose the offer you want, the new expiration date will come up. I booked my Nov reservation with the $30 off code and Alamo accepted it with no problem. Also, printed out he coupon just in case but when I clicked on "reserve now" the Alamo site filled in the ID and code atomatically, so I don't think this is an error.
