1. If someone contacts you that you don’t know and they send you money, and then ask for you to send them money back. That’s a scam! Pure and simple.
2. To research viable mystery shopping companies, please visit The Mystery Shopping Provider Association of North America: http://www.mysteryshop.org. However sometimes scammers will use legitimate company names. This brings us back to Rule #1.
3. Mystery Shopping companies will NEVER pay you before completing a job. Nor will they ever ask you to send them money! (yes, rule # 1 and #3 are similar!)
