I think their shipping windows are often just messed up.  I&#x27;ve had the opposite situation too, where it says that an item must be ordered within the next 2 hours and then when I get to checkout the window is already passed for the day.<p>I&#x27;m wondering whether the ship timer on the item page isn&#x27;t quite accurate, and the one on the checkout goes through and does a warehouse-by-warehouse check to see where the nearest warehouse that has stock <i>and also isn&#x27;t closed</i> is.  As east-coast warehouses close you might get additional availability windows from west-coast warehouses, and their algorithm might not be doing an exhaustive search of when <i>the last possible warehouse that has stock</i> will close.<p>I&#x27;m not saying that it isn&#x27;t a dark pattern, but there are still some &quot;incompetence&quot; explanations before we need to jump to &quot;malice&quot;.
