Sounds like YMMV to me. I just logged in and my log shows 168 shops (out of 252), dating back to 2012. I've never had issues with them as far as getting paid, though I have been dinged for them having to request additional info (mostly due to less-than-optimal wording on their part in their forms). Their shops are not the most lucrative, but I don't feel they are grossly underpaid. The only ones that I didn't feel was worth the pay were hotel audits. A lot of work and a lot of pics for only $25. When they came up again, after multiple begging emails from the scheduler, I offered to do a route of them for a sizable travel bonus, and was turned down.
I do have a current issue with them re: credit union shops. Awhile back they changed the scenario where you are supposed to go through the interaction then be unable to produce a picture ID. These wind up being pretty easy money, as usually the rep will ask for ID straight away, meaning the shops last about 5 minutes. They used to pay $12, but now they pay $10. No biggie since the time involved on site is short, and the report takes about 10 minutes tops, including scanning business cards.
I did a couple of them today, and noticed that, while the solicitation and the Shop Pay on the left hand side of the form was for $10, in the Shop Overview on the right side of the same page remains unchanged at $12. So somebody did not exercise the accuracy and attention to detail that the company expects of their shoppers (LOVE when that happens!)
I emailed the scheduler and requested the extra $2 per location because A) they screwed up with their documentation, and
I should get a little something for bringing the error to their attention. Will be interested in seeing how it turns out.
Have synthesizers, will travel...
