sales funnel question
So I am going to affiliate market some online courses. There is no sales funnel. I bought a course this morning and it took me right to a Paypal payment page. There are good courses for various niches and I think I may do OK with it. As an affiliate of theirs am I stuck just promoting the courses?(which is OK) or is there some way to get a sales funnel of my own going with affiliate products? I have no products of my own. They have some free courses that I guess you could just give away to your list, but then there is no back end. Is there a way to do this with their products or not?
Thanks
Scott
