Sub ID's are a way to create an affiliate link for (1) specific product vs the entire store. When you become a Spiritech Specialist or Ambassador an affiliate link is assigned to you to share with your potential clients in order to show them the products you now represent. This affiliate link, however, displays the entire store so if you need to take a client to a specific product you will need to create a Sub ID.
