title: pay on arrival in Django Oscar?
body: <p>So I customized Django-oscar, everything works fine until the payment step</p>
  
  <pre><code>Enter payment details
  This page needs implementing within your project. You may want to use one of Oscar's payment gateway libraries:
  
  django-oscar-paypal
  django-oscar-datacash
  django-oscar-gocardless
  django-oscar-paymentexpress
  django-oscar-accounts
  Continue
  </code></pre>
  
  <p>I do not want online payment, my courier will send the package and collect fees. Is it possible to config django-oscar to accept pay-on-arrival style of payment?</p>
