I've done it in the past but I never had to invest anything other then paying for the item or services rendered which I was reimbursed for plus pay for doing the shopping in the first place.
I've never done it but where I use to work (Sunglass Hut) we got mystery shopped every other month. I don't know that much about it but I did look into it as a second job and I couldn't cuase I worked at a place that used it. A friend of mine use to mystery shop Mc Donalds and would bring me free lunch a lot cuase he got sick of eating it all the time LOL. I know that I hated being mystery shopped LOL. We had a sheet we had to study. I got a 100 only once. My first score was a 14 but the lady was drunk.
I have and still do them. I have never had to pay money to get started. I just pay for the item they want you to buy and then get the money back plus commision or a fee back.
