But in general you do not need to pay anyone for anything to establish a successful mystery shopping business. You will find lot you need here, free for the taking. Realize that Jobslinger covers fresh listings for only SOME companies and draws also off of public job boards. Generally the shops that show up on public job boards (whether here or at the MSPA or at Volition.com or elsewhere) are ones where there are a shortage of shoppers in an area or are jobs that have a problem (fee, requirements, promptness of the company paying/reimbursing etc.). Everybody is trying to make a buck but you don't necessarily need to give them yours.
