Shadow Shopper is not a Mystery Shopping company, they just inform you about job openings. You can sign up with multiple companies and find the jobs yourself. I don't believe in paying money to find jobs.
Shadow Shopper was a headhunter back in the day. I started with them, they sent me jobs only in my area, and I took
everything and learned. I even got my Silver Certification through them for 15.00. They have changed, I don't use them
anymore, but think they are a good stepping stone.
