It makes sense that a transition to accept bitcoin would be underway for more US-based stores.
Soon I bet. I have read somewhere in the forum that Amazon is already considering bitcoin as payment for the products and services that they offer. In addition, more and more online shops and payment centers already accept the online payment by convertion from bitcoin. Therefore, it is quite sure that they'll accept it soon.
