I have been doing mystery shopping for over a year now. I started out by taking the easy & low fee shops such as bank shops, now I have hooked up with different companies and making $20-$40 shops.
I still do shops for Bestmark but only as an additional shop if I am in that area. I have never taken any of their big jobs no matter what the pay.
I like mystery shopping and I plan to make more money doing it.
