My guess:<p>- They cost more than the free shipping threshold, giving shipping away free<p>- New games are low profit to begin with<p>- Amazon sells enough of these that they are already in every distribution center<p>- Every unit Amazon ships probably arrives in a &quot;Prime&quot; amount of time anyway, giving away expedited shipping for free<p>This is just bringing some video game sales into alignment with what Amazon wanted Prime to do all along.<p>Amazon makes very good money on a sale that they don&#x27;t control. If the costs of making that sale (or supporting returns, etc) is too high they benefit significantly by letting marketplace sellers take all the risk.
