Telephone shops--if they want you to record the call you are usually dialing through a toll free number to place the call and have it recorded by the company's system.
Almost any of the companies will have some shops with minimal or no purchase requirement. Banks vary across the country so it is catch-as-catch-can what companies shop your area. Keep in mind that Jobslinger.com is a guide to who shops in your area and really doesn't work well as a job board because of the prevalence of its use. The jobs posted there are gleaned off MSPA and Volition job boards in addition to those SASSIE companies who authorize SASSIE to release the data to Jobslinger. The jobs you will see there are either hard to place (thus get posted to the MSPA and Volition job boards) or from some SASSIE companies. I feel that the best use of Jobslinger is to see what companies are active in your area to sign up with first for new shoppers. Once you have shopped for a while and decided to stick with it, it is time to go through the lists and start signing up with a lot of companies. And no list is full, complete and accurate, so keep your eyes and ears open for new companies.
