Hi, stormmy, welcome to the forum. Being a mystery shopper means you are an independent contractor and you do all the work of applying with companies and finding your jobs yourself rather than being an employee who works for one company doing what a supervisor directs you to do. You will go online and sign up with different companies, providing your personal information and SS# and you will sign a confidentiality agreement. Then you will be able to search their job boards to find jobs for yourself. Read all the threads above your entry that are marked "sticky" for more detailed information about how to run your business. When you are getting started, it takes a lot of time to read everything and apply with many companies. Read very carefully and start slow. This is a fun and interesting way to make some money but it's not for everyone.
