I did for a couple of months. I can't remember the name of the company but I know that I signed up over the internet based on info I heard on our local news. I was given assignments to mystery shop the same store 3 or 4 times. I was always given the same scenerio of questions. Needed to be acknowledged by an employee of the store and then I'd need to ask that person a direct question. Always had to go to the pharmacy window and ask advice. Always had to inquire about their 1 hour photo service. Always had to rate the check out person. I felt that the assignments were not all that interesting and besides, I was being sent to a small store where I started recognizing the employees. I felt that if I was recognizing them, they had to be recognizing me -- how many other people come in there every month and inquire about the 1 hour photo and never have any film that needs to be developed?? It really was quick work. It did pay $8.00 and covered the cost of an item I had to purchase in the store for $2.00 or less (usually a greeting card). Anyway, it wasn't for me. I had hoped that after the first assignment I would have earned my way up to something a little juicier but it didn't happen. Good luck with whatever you decide.
