You can use purse.io to use Bitcoin to buy things with Amazon - I believe they guarantee your order will get filled within 24 hours if you ask for a 10% discount.
Using this site is not without risks.
i see, thanks for your advice
While this will allow you to buy things at a discount on amazon, it is not without risks. You are risking the fact that a stolen credit/gift card was used to buy your goods. While the person buying the goods for you would not get access to your bitcoin until you actually receive your goods, you theoretically could get into some amount of trouble with amazon and/or law enforcement if this were to happen
