title: How to remove delivery shipping step on prestashop 1.6.1?
body: <p>I'm new to <strong>prestashop</strong> and I'm having major trouble removing  the delivery shipping step because I only sell virtual products. I am using prestashop 1.6.1.</p>
  
  <p>I know I have to modify <code>order-carrier.tpl</code> file and have followed several posts here and there but couldn't get it done right.</p>
  
  <p>Does any of you have any actual idea on how to do this ?</p>
