How it works:

• Manage Advertisers: Add new / edit existing advertiser, such as shoes.com (GAN), drjays.com (GAN), ...  endless.com (CJ), this will populate the table affiliate_advertisers (advertiser_id, advertiser_name, advertiser_filename, affiliatenetwork_id, ....) with the new advertiser's information.
• Create Mapping: in this step you will be asked to create a relationship between column names (from the CSV ) and Magento attributes.

  The version we have released on March 12, 2014 allows you to map multiple columns.
  For example:
  If you associate:
  ADVERTISERCATEGORY with main_category
  THIRDPARTYID with main_category
  THIRDPARTYCATEGORY with main_category
  the plugin will combine ADVERTISERCATEGORY , THIRDPARTYID and THIRDPARTYCATEGORY and use it as product category (very handy if you wish to assign products to the right categories).
  This feature also allows you to create SEO product names, descriptions, because it allows you to combine multiple columns.
  For example:
  if you map NAME, DESCRIPTION and SKU to name, the product name in Magento will be created using NAME, DESCRIPTION and SKU.
  
• Download Feed: On this page, you will be asked to choose your affiliate network (such as Commission Junction, Affiliate Window, PerpperJam Network, or ShareaSale.com networks, Custom Affiliate Network). Once selected, a new dropdown list will be filled with advertisers for the selected affiliate network. So, if you are affiliated with shoes.com through commission junction, and you added this advertiser in the first step, selecting the Commission Junction will cause shoes.com to appear in the list. Once selected, you will need to click the button “download feed,” which downloads these feeds to the folder feeds which is located on your magento root directory and saves it to the database.
• Create Importable Feed: You will be asked to select your affiliate network. Once you have selected your affiliate network and pressed the "create an importable feed” button, the script will create a new CSV feed called productsFeed.csv and located in the folder var/import. Magento dataflow knows how to use it to import products.
• Import Feed into Magento:You will be asked to pick a date for your imports. If the button "Schedule Affiliate Product Imports" is pressed, the imports will be scheduled to automatically run at the selected time through the cron job. You will be notified when the import is complete. . 
• Catalog update. This will use Magento cron feature (No additional cron setup is needed). For all  items (in magento store) the module checks the magento price , compare it to the price  saved in the database. If the product in no more available, it will be deleted. If the Magento price is greater than the database price, the magento price will be replaced by the database price.
