Forgive my ignorance, but does it matter that AS doesn't support "smile"? Smile give a percentage of your purchase price to the charity of your choice, but you can't purchase anything through AS. Or can you?
You can in fact purchase through AS, as the AMZ side is a basic browser. However the title itself will NOT be immediately available. You will either need to reload the page, or AnyStream. As AS can only download titles that were available to your account AT AS STARTUP, or initial loading of the page.
