To be honest shadowshoppers is what really introduced me to this business. Even though now I am signed up with almost 50 companies, I like that they constantly email me about jobs in my area. It helps that my city is midsize and not a major city, so anyway I can find out about new assignments in my area is worth it.
I also get emails and calls from time to time from people looking for shoppers or merchandisers in my area.
So to me the money I pay every 3 months is worth it.
I can see how it is not worth it to others though.
