Except for every single brick & mortar store -- which has always been Amazon's biggest "competitor".

(Note: that growth is still a good reason to be bullish about Amazon!)
All auto sales, gas purchases, alcohol & tobacco, heavy industrial equipment (commercial farm equipment, etc) are included in that category.
Online sales only being 10% of that still probably looks massively outsized if you're drilling down to B&M clothing & electronics purchases. I haven't made a B&M retail purchase any more times than I can count on one hand since 2004.
Amazon and Uber are very different companies, but this wildly oversimplifies the financing of Amazon. Amazon has taken on many billions of dollars in debt over the years in order to operate. If you add it all up, Amazon has taken (in very different terms) about as much money as Uber.

Amazon is also very different from Uber in that it a) went public earlier and b) didn't need huge outside cash injections like Uber and c) Wasn't making a huge gross loss on sales like people claim Uber is.
I believe Uber has already lost more money than Amazon has in it's entire existence!
