Yes, you need to be approved by each network and merchant that you promote within your stores in order to earn commissions. For example if a portion of your website is focused on athletic gear and you want to promote products from Adidas who is a member of the Commission Junction network, you would first apply and become a member with Commission Junction. Once approved, you would then apply to the Adidas affiliate program. Once you have been accepted by both you can use Sellfire to create stores to optimally promote the Adidas products yielding higher sales and commissions.
