Shadow Shopper. It is a debate that will continue. I have signed up with them on the free package only. I do not think you should ever waste your money on what you can get for free. They promise you more and better jobs. There is a benefit to it. Did you know that just by registering, your name gets added to the database of shoppers? This is a benefit for a few reasons. You will still receive some email offers. In these emails, you will see name of other companies to register with. Schedulers can access the database to find shoppers in areas that they have shops. I just received an email this morning for someone who had a free spa service shop near me. I signed up. I will be off to get my nails done on someone else's dime shortly. The promise that by becoming silver and gold you will get more job offers. Most companies will not pay Shadow Shopper to list their jobs. They list them on their own website for free. How can you find different companies? You may search here. You may also look for jobs on the MSPA site directly. Another great site is www.jobslinger.com Jobslinger is a major job board where schedulers from all over post their available shops. You can search by your zip code. I find the MSPA site awesome for this too. Their site is www.mysteryshop.org You may view their job boards and also their forums for shoppers. I promise you will find some useful information there.
The bottom line. Don't ever pay to be a shopper. Don't ever pay to access jobs. You are in this to make money. Remember?
