title: Magento (v 1.7.0.2) - Add "Shipping Method" column in Sales Order Grid
body: <p>I'm trying to add a new column for Shipping Method (Standard, Priority, Express) in the Sales Order Grid located here:</p>
  
  <p>/home/html/app/code/core/Mage/Adminhtml/Block/Sales/Order/Grid.php</p>
  
  <p>I've researched tons of methods but either it's for an older version of magento, or simply doesn't work. From what I understand, I need to do the following:</p>
  
  <ol>
  <li>Edit _prepareCollection()</li>
  <li>Add a case in _prepareColumns() like the following:</li>
  </ol>
  
  <p><code>
     $this-&gt;addColumn('shipping_description', array(
              'header' =&gt; Mage::helper('sales')-&gt;__('Shipping Method'),
              'index' =&gt; 'shipping_description',
          ));
  </code></p>
  
  <p>Can someone please help me get this figured out?</p>
