"Billions and Billions", To Quote Carl Sagan
Check out this article on Amazon Prime's massive amount of shipments during 2017. Amazon keeps secret the total number of Prime members, but third-party estimates say ~90 million in the US alone (yes, including me). Does this include virtual "shipments" of downloaded products (books, apps, etc)? Either way, Amazon's software and hardware infrastructure scale is amazing to behold.
