I don't understand what you are asking about?
If you are using E-junkie to sell your own products online, the Add Product link will take you to a Product Configuration screen where you would define what your product is. I don't know what you mean about having an "add products page"? Our Getting Started help page is a good place to begin setting up your E-junkie service to sell your own products:

If you are using E-junkie to participate in another merchant's affiliate program, where you would earn commission by referring sales for another merchant's products, then you do not need to pay for an E-junkie subscription, and you will not need to use the Seller Admin (where you are seeing the Add Product link, etc.). Instead, you should click on the Affiliates tab at the top of our site to switch from Seller Admin to Affiliate Admin, then follow any instructions your merchant has provided. This page explains the most basic functions of using the E-junkie Affiliate system:
