I was a stay at home wanting to make some extra money. I by chance read a couponing blog that mentioned mystery shopping and the MSPA. I did some google research and found the MSPA website. I started there with companies because I could plug in my zip and companies with jobs in my area came up. From there I read the job descriptions and went to the companies to apply for them and the jobs.
After a couple months I worked with 3 companies. I researched scams one day and found this forum. I was extremely overwhelmed when I first started reading. It was like a mystery shopping super highway. Info was coming at me 100 of facts a minute. I would recommend to read here. I would take the good and the bad and make your own informed decision. If someone is complaining, how many posts do they have? Are they all complaining about the same mishap or many mishaps or does that person have something else to share? We all have a mishap every now and again, but does the good out weigh the bad? That is up for you to figure out. Take it slow. Get your feet wet and go from there.
My first job was a car dealership for $14. I loved it. My second day of mystery shopping was my first route with 10 banks and a restaurant. WOW! I was overwhelmed, but loved it. Alot of companies wouldn't give a newbie like me a route with so many of their trusted clients until you proved yourself, but apparently they really needed people in this area and pounced on me. I guess I was worth the chance because I still do their banks and more.
Good luck, have fun, and be safe.
