Amazon is a non-union company and they have almost single-handedly destroyed physical retail in the Western world. Amazon has created immense value for consumers and shareholders, Jeff Bezos would not be the richest person in the world if Amazon was not good at what they do. Costco hasn't innovated in decades, if it all.
Is that a good thing for real? From what I heard Amazon no longer will have lowest price on things. So essentially isn't this a big bait and switch strategy. I do thing in the long run Amazon's near monopoly on things will come back to bite customers as they will destroy the competition. The example of co-mingling of stock is one example. So much customer harm and fraud and they still do nothing because customers still buy from they for comfort. Any smaller company would have destroyed doing that.
I was a big fan of Amazon till I saw the behind-the-scenes cost. I agree totally Costco sucks at innovation. They missed huge opportunities. I got a few more ideas. Might try to sell them to them.
