http://www.volition.com . Click on forums and check out the Mystery Shopping and Merchandising sections. I worked for Merchandising and Mystery Shopping for a few years before I had to quit to help take care of my Dad each month for a week. I got my start from this website and the information is free.
Hope it helps until you get the job you want. Hey it is a good way to get extra cash for stash too. It is very flexible work too.
