Complaint Review: Mystery Shoppers USA

Mystery Shoppers USA mailed me an opportunity to pay their $29.90 fee. I declined to participate. I took the time to look up the name of the enterprise on the web.
I was unable to find a web address nor a telephone number in their bulk mailing nor on the web. Curious.
I was able to find a "Mystery Shopper USA" on the web. Mystery Shopper (singular) appears to be based in Florida.

I have no reason to disparage the "Mystery Shoppers USA' organization. But until the rants of Russ, Bobbie and Paula are rebuttled by the company I think I will hold off from joining their august organization.
