Hi Charlie, first you have to sign up with some of the companies on the official list (link at the bottom of the page). Each company has guidelines for various shops. After you get accepted for a shopper and get assigned some shops in your area, the mystery shopping company will provide you with guidelines and a report form that you will fill out on their secure website. Different MSCs have different types of shops that vary in degrees of difficulty and will have different amounts of pay. I would suggest signing up with Marketforce as a place to get started. They have pretty easy shops so you can learn and get comfortable.
