value of a course -vs- features of a course

I would like help on how to convey the value of my online course to my potential customers. Is there a class inside scholars that goes into this more? I want my customers to know they are getting that Mercedes for $10 but then I list the features of everything they “get” inside the course. How do I bridge the gap between the value to the customer of the course and the features of the course. Thank you!
