Looking for Part-Time Work

There are MANY scams out there for work at home jobs. I searched for data entry because I do have experience in that. I also looked as far as a mystery shopper. To even look at a mystery shopper data base it would cost me $17.95. I do not know if there is a legit work from home job unless you are an entrepreneur. Has anyone done mystery shopping? I don't understand that if you go on the big job search engines they provide you with so many gimmicks for work at home jobs. I think it is ripping off honest people who are looking for work. It is a shame.
