title: Difference between product discount and special in Opencart
body: <p>I have different customer groups and have set special price for each group. </p>
  
  <p>When I set <code>special</code> price on a product for a group and login as a user from that particular group in the shop's front-end, I can see the new special price below the original price.</p>
  
  <p>However when I set <code>discount</code> price on a product for a group and login as a user from that particular group in the shop's front-end, the new price is not shown in the product list but the price is discounted on checkout.</p>
  
  <p>Is this how it's supposed to work?</p>
