A lot of people have been clamoring for Amazon to consider accepting Bitcoin as one of the mode of payment available on the giant eCommerce site but until now it seems that Amazon is not really interested. And it can be because they know for sure that the market is not that viable enough...they know that other merchants have done the same and the business volume they experienced is not really impressive. Amazon is business, they want to make money and they know when it is time to be a part of the bandwagon if they can see one.
