I probably missed Amazon's announcement about this, what I saw is they are denying accepting BTC after some claims... I tried to search about it now but didn't find anything except a few report denies!
Well, since I am in crypto every year there's a talk about Amazon will start accepting Bitcoin... and nothing happened until now, so I doubt they will do it! I guess their business is flourishing anyway, so why would they change anything and cause some problems?! And let's be honest, choosing Bitcoin as a payment option would be a poke in the eye for many countries where they operate and make a profit! So, this will not happen for now, maybe one day in the future!
