&gt; Did Amazon once offer free shipping to people who didn&#x27;t have Prime?<p>Yes.  It wasn&#x27;t next day delivery.  You still get it, but there&#x27;s a minimum spend requirement now.<p>&gt; I&#x27;m pretty sure that they can&#x27;t just change the benefits of Prime in the middle of my membership.<p>Don&#x27;t they have a clause saying they can change the terms whenever they like?
