Goog just launched one day delivery and it has a lot of muscle power. But ebay business model competes directly with amzn. Amzn actually came after ebay by copying them.
Neither, amazon will destroy amazon. it will be their own arrogance, low margin business model, retaliation to their poking at compeditors and finally a cash crunch, maybe after some event or political catalyst.
Lets not forget about tax
Brilliant response. Once AMZN does not serve Wall Street's need for a swing stock...they will be pummeled..
