So should we have been buying from Amazon's competitors instead, even if they have a worse selection, worse customer service, few if any reviews, slower delivery, and are much more inconvenient to buy from? Variety, choice, and a healthy competitive ecosystem are definitely desirable and to be missed with Amazon's dominance, but there are many reasons Amazon is ahead of other e-commerce sites and brick-and-mortar stores. It'll be interesting to see if/when Amazon finally starts to seriously increase its prices once the rest of its competition are dead and there's no where else for consumers to go. Will there be a reckoning? Will Amazon be split up?
