Completely for free. I don’t trust having to send 19.95 to some random address! I read an article a long time ago in a local publication that there are some legit employers of that sort of business, and there is some website with job listings that doesn’t charge. Have any of you done mystery shopping, really?And have any of you been ripped off by some “mystery” employer? If this question doesn’t have a positive answer, what are some actual jobs I could do in my rarer free time to make a little extra money? My job hours are very part-time where I work, and I am afraid of mounting expenses.
