It&#x27;s a good point.<p>But I&#x27;d challenge you on your assumption that this is a bad thing for stores and consumers.<p>It&#x27;s a powerfully negative experience to buy something, and then find out within a few days (or hours) that it&#x27;s selling for far less. It happens millions of times per day (www.forbes.com&#x2F;sites&#x2F;walterloeb&#x2F;2014&#x2F;11&#x2F;20&#x2F;amazons-pricing-strategy-makes-life-miserable-for-the-competition&#x2F;), and most people don&#x27;t find out. But the reality is that it&#x27;s happening.<p>A customer could return it for free (and re-buy it -- many states require this by-law). Or a store could do good by the customer and give a price adjustment.<p>It turns out that when stores do good by customers when this happens, shoppers become far more loyal (and spend FAR more on average too, growing store top-line &amp; often net bottom line). This is part of the secret of Amazon Prime.<p>While I can&#x27;t claim that it is the right or only view, I fully believe that stores will benefit far more than the costs.<p>*Revised based on mquander&#x27;s feedback
