A9 gets you discounts at Amazon.com
In yet another really smart move, Amazon has implemented an awards program for using their search engine, A9. Here is the text of the notice that I saw on their website:
Ray Grieselhuber, since you’ve been using A9.com recently, virtually everything at Amazon.com is automatically an additional Pi/2 (1.57) off for you. Collecting this discount is zero effort on your part. It will be applied automatically at checkout (it will happen whether you use the shopping cart or our 1-Click Shopping®). You don’t need to do anything to get this discount except keep using A9.com as your regular search engine.
We don’t advertise this additional discount that we give in exchange for using A9.com, so if you want your friends to know about it, please tell them. It is probably the only way they’ll find out. All they have to do is use A9.com as their regular search engine. They should make sure they are signed in to A9.com (it should be recognizing them by name) so that we can be certain they get credit for their visit.
