I tried to use this code in Ithaca, NY on the 29th Oct. but the rental counter did not have an Avis Preferred folder waiting for me. I was forced to stand in line, and the agent who handled my reservation informed me that this code was invalid because Avis had advised them that it was fraudulent and being used by anyone who had information via blogs....
He said the only rate I would qualify for at the time would be a AAA rate which was just as expensive as no code at all.
