Hi, carrieout, welcome to the forum. There are a lot of mystery shoppers, and many shoppers face a lot of competition for a limited number of shopping assignments in their area. The most time-consuming part of MSing is researching and building and maintaining a MS client list. Many shoppers invest a significant amount of time in this research, so their lists are valuable. Most do not share their lists with others who live in their area, because it then increases the already-stiff competition.
How many companies are you registered with? And how recently did you register? If you registered less than a month ago, you may be registered with companies that have assignments but they are already assigned for this month. For the best volume of shops in your area, register with at least 50-100 of the companies in the list at the bottom of the page. Many of us are registered with 150 or 200. Check out Jobslinger for some companies in your area. Plan to work hard and spend a lot of time getting started and getting your list set up.
