I became an independent contractor or mystery shopper for Market Force a couple of months ago and so far I am very impressed with their company.  Their shopper site is very user friendly and easy to navigate around in.  There is always work that needs to be done and the shop fees range from anywhere to $3.00 to a simple 1 minute phone call from your home all the way up to $45.00 for snapping some pictures of your local Exxon. You can shop for companies such as I-Hop, Pet Smart, Exxon, Domino's Pizza, and Holister to just to name a few.  Of course you need to submit your results of your findings...
