That&#x27;s not clear. The idea that (non royal-patent) monopolies always pursue dominance to corner price seems problematic.<p>Like Standard Oil, Amazon is ... obsessively keeping margins down for the sake of keeping margins down. Who would have to fall by the wayside for them to &quot;win&quot;? WalMart?<p>Don&#x27;t look now, but WalMart has quite the online retail presence. I&#x27;m not sure how to evaluate the advantage&#x2F;disadvantage of &quot;in store pickup&quot; but I&#x27;ve used it for big bulky things, when I&#x27;d needed better control over when I took possession of the item.<p>Meanwhile, Amazon&#x27;s effect may well be part of our increasingly deflationary economic cycles.
