Don't you think that there's a value in posting an honest opinion? What's the difference in the free burger you just got for mystery shopping?
I've done mystery shopping for over ten years and other than Coyle and Bestmark, most aren't even worth your time. At least this way we get things we want/need...
What is the purpose of mystery shopping? To give your unbiased experience - same as reviews online - IF you are honest.
So I know a company/individual that pays to do online reviews - like mystery shopping in that you get reimbursed for your purchase and then post a short but honest review.
Not sure the best place that I can let people know about it. You can email me if you want to do them at stephanielarson44@Hotmail.com - I was told they have a lot to do.
