Not to mention online ordering of goods. When I buy something at the store, I have to drive a few miles to a store. That store serves an area of several square miles, and there is another store to serve the next several square miles. Each of these stores must be individually stocked.
When I order something online, my item is shipped from a central warehouse to a shipping facility in my city, which serves an area on the magnitude of hundreds of square miles. That shipping facility calculates an efficient route based on all of their deliveries for the day, and the item gets delivered to my door by the same truck that delivers to several other people in my neighborhood.
Certainly, delivering data electronically is considerably more efficient when it's possible. But even for tangible goods, ordering something over the internet is more efficient than buying it at the store.
