There&#x27;s a positive externality that arises from price-sensitive shopping.  It promotes competition, which leads to lower prices for everyone.<p>If everyone behaved like you, requiring a 40% discount before moving away from Amazon, then Amazon would just set its prices 1&#x2F;.6 = 66% higher than the other stores.  Fortunately, not everyone is like you, so Amazon&#x27;s prices are often competitive.<p>To some degree, I suppose this is like buying index funds versus buying individual stocks.  I only buy index funds.  But the reason I can get away with it is that there are at least a few people out there searching for value.  I can&#x27;t compete with them.  But I can price-compare online, or at gas stations, etc.  I see shopping for low prices as part of my duty as a capitalist. :)
