According to this page, there is a promo where you can get 10% of the value of your rental back in Amazon gift cards when you link your Amazon account and book through that. I had a rental in December where I did this, followed all of the instructions, and never got anything. I have called Avis a few times now, and no one has any idea what I'm talking about. Is this not a real promotion? If it is, has anyone actually gotten their Amazon gift cards?

Thanks!
