title: Order Mangement System for CodeIgniter
body: <p>I am developing a online store application, which provides customized products, on CodeIgniter. I was looking for a possible shopping cart application that I can integrate with my app. 
  I understand that CodeIgniter has its own Cart Class. But it does not provide any credit card management facilities. And I would like a system which takes care of shipping, order management etc.
  Are there any options out there?</p>
