title: Change Shipping price while editing order- Magento
body: <p>I build a custom module for shipping that has several price options. It works well in frontend. </p>
  
  <p>But when we need to edit an order already placed in admin, I cant get the custom prices. It always shows the default price only. </p>
  
  <p>How to overcome this situation? I searched for a while, but does not got any solution.</p>
