I did mystery shopping for some time.
It is done through companies and the idea is to evaluate how certain stores/business are doing, if they meet some standards, etc
basically you get the instructions about what needs to be done, for example a gas station. You go to the station without identifying yourself and review things like, store appearance, employees wearing uniforms, products available, etc. the you fill a report, usually with pictures to back up your report.
The pay varies by company, tasks, etc it can go from $5 to $40 or maybe more, plus any items you were asked to buy
hope this works
