Hey!
I know that we can pay with btc in Amazon, Tesla Motors, Kmart and Zappos.
You can buy with btc directly on Amazon? I've never heard of that. Are you sure ? Or this is just a sentence you copied from somewhere else?
i hope OP answers but i have seen one other person say this too. i asked that other person and he didn't reply!
i believe they are talking about Amazon gift cards that you can buy from third parties and spend it on Amazon, not directly though. and i have never found anything on Amazon website either. so if i have missed some news it would be great if someone could give us some links.
