She gets a following making mystery shopping look easy. She then convinces people that they should join her course because she will guide them through the process and hook them up with all the mystery shopping companies.
The people that join the course are either going to waste their money when the realize that there is so much more than what she shows and they won't put in the effort. Or they are going to join her course and qyickly find out everything she is teaching them is free if you put a little work into the search.
She is making money so good for her, but i do feel bad for the people who believe that they need her information to succeed. Almost everything is free somewhere on the internet if you put the effort in and if you don't have the effort to google mystery shop companies and instead use that effort to put in a credit card number, you probably won't take the effort to make routes, and write good reports so you can be profitable.
