title: Cannot get product availability
body: <p>I'm trying to display availability in the order confirmation email, that is sent to the client. Anything I've tried so far, is not working:</p>
  
  <pre><code>$_order = $this-&gt;getOrder();
  foreach ($_order-&gt;getAllItems() as $_item):
  
      if ($_item-&gt;isSaleable()):
            echo $this-&gt;helper('catalog')-&gt;__('In stock');
      else:
            echo $this-&gt;helper('catalog')-&gt;__('Out of stock');
      endif;
  
  endforeach;
  </code></pre>
  
  <p>I've also tried 
  $_item->getStockQty();
  $_item->isAvailable();</p>
  
  <p>Why is this not working? Could you help me please?</p>
