Amazon's to consumer revenue should include it's online stores (262billion), sales of third party products (172billion), physical stores (22.56billion), and i think subscription right (amazing prime, 50billion)?

Where do you get 5% from? That again doesn't pass the smell test.

Amazons b2c is Alexa, Kindle, Video, Music, Store, Whole Foods and a bunch more. Its revenue is about 350b annually, just shy of half their revenue.
