It would be great to put a headline, image, description, and button INSIDE of a course to go to the sales page for another course. Kajabi has the ability to do this. It makes it nice because your customers are inside the course consuming what they purchased, and when they see the little "advertisement," it makes a lot of sense for them to jump into the next thing. We can even give them a special link that gives them credit for what they just purchased, promoting a more expensive offer.
