They often are referred to simply as TRS. The only shops I have seen from them are signing up for things like Stamps.com, Netflix.com etc. on line. You get to do it once only if I recall correctly and you need the discipline to make sure you cancel your 'membership' promptly or you will find yourself getting nicked subsequently for your "membership". I have never worked with them, though I am signed up, because these are not reasonably paying jobs and feel to me (opinion here!) like an attempt to expand membership on these things rather than evaluating them.
