Boy, did you get some great responses from schedulers and other shoppers!
I constantly receive e-mails for phone shops; kudos to anyone who can complete them. I hate them; I've tried probably 100, and failed miserably. For example, I reported on one shop the agent was professional and businesslike. The editor who listened to my call called me to tell me the woman on the receiving end of the call was just a b****! I was shocked. She added I was way too nice, too chatty, and should just shut up.
Intelli-shop has dozens. IPSOS has thousands (I initially wrote dozens, but there's 6 pages just in my state, and another six for Colorado, and even more for Kansas!), high pay, too, especially if you don't mind calling a bank to complain.
Absolutely not my cup of tea. When I was going through really tough financial times, and no car to go mystery shopping, I worked on them over 100 hours. I earned $35 total, and that only because the scheduler pushed through some shops I didn't do well on.
I'd rather eat liver than try it again - and I really, REALLY hate liver!
