Hi all, I am interested in learning Prestashop but cannot figure it out. I come from a strong open source background specifically with oscommerce and virtuemart. What I am interested in is the feature list and its management. If you look here http://www.prestashop.com/en/allfeatures/ you will see "Cost per click management, fixed fees per order or percent of the order" but I cant find anything in the demo store online that has that? What is it and where can I learn more?
