Well why do we need Amazon to accept bitcoin? Anyone could use bitcoin to buy off amazon for many years already! You can google "bitcoin amazon io" and you will be brought to the purse website, which has been around for the longest time allowing users to purchase amazon products using bitcoin at a discount. The only concern is the legitimacy of the funding source (whether people are using scammed amazon gift cards to buy the products on your behalf), but I think most users have had fairly decent experiences buying off them.
