Amazon has been quite useful for me as a single bachelor living in an Indian metropolitan city.

1. I get very useful items at very good prices, many of which I would have to wander the city for hours to find, or couldnt find at all: - Eg: I got a pair of adjustable dumbbells at <2K INR. Some of you would call it a cheap knock. But it has been super useful and I would have not bought it if it cost 8k INR. I brought a whole bosch repair toolkit at good price and it has been invaluable for fixing electric/plumbing etc.. issues. I got a high volume travel bag - I didn't even know 40L travel bags existed and wouldnt have brought one if not for amazon. I could go on.

2. Amazon Fresh is usually cheaper for groceries and maintain consistent quality compared to local supermarkets. I will also avoid the need to walk long with the grocery bag.

3. Electronics are significantly cheaper on amazon and again the need to search.

Maybe all of this can be even better as you said. But bottom line is that their operations look pretty efficient to me. Their catalogue is pretty much unmatched. (They may be losing money on retail business - but that's not my position to care as a customer. As other commenter pointed out, it may not even matter much for stock price.)
