title: Display All On Sale/Special Price items in Magento
body: <p>If you want to set an item "On Sale" in Magento you have to set a "Special Price". Special prices enable you to define a discounted price for a product for a specified period of time.</p>
  
  <p>My question is how can I add a link in my layered navigation to display all my "On Sale"/"Special Price" items. </p>
  
  <p>Thanks</p>
