title: Get row total price from a configurable product in Magento
body: <p>I'm writing a payment module, and after the checkout process I'm doing the following to get the price for each product.</p>
  
  <pre><code>foreach($order-&gt;getAllVisibleItems() as $item)
  {
  //...
  $price = (float)$item-&gt;getData('row_total_incl_tax');
  //...
  </code></pre>
  
  <p>Afaik it works with any kind of product except configurable ones. How can I retrieve the row total for a configurable product?</p>
