You have to admit, making a comment that you are too lazy to scroll down invited the response.
Mystery shopping, other than video, can be started with low to no cost. OTOH, there is a lot of sweat equity which includes learning how to approach it as a business.
Keep in mind, there are a lot of shoppers here with a combined decades of experience. Everything from the hobby or lifestyle shoppers focusing on fine dining, to those using it for supplemental income and even some who make a living with just mystery shopping. What some shoppers still don't grasp, there is much help and even much work to be had from fellow shoppers. Personally, I have had several long-term, ongoing and lucrative projects as the result of relationships with other shoppers. For those type of special projects the companies prefer to look to their existing shoppers rather than post randomly on job boards.
