Sometimes when new shops that I haven't seen before pop up, I'll do one if they seem interesting to me. Even if the fee is low, I consider it an investment in my business: How much time does this shop take? Is it really as interesting as it seemed before I did it? Are there lots of locations near me that will be shopped? What fee would make this worthwhile for me to take and how often would I be comfortable doing it?
I've found lots of jobs that I really like this way. I've learned that some shops aren't bad, but need to be bonused to make them worthwhile to me. And I've learned which shops to avoid this way, too.
The real value of that $10 shop might be the knowledge that you learn about that particular shop (which can be extended to shops like it), and not the 10 bucks. If it was bonused this month, maybe it will be bonused again next month! And if you've done one before, the scheduler might be more likely to give it to you with a bonus. Either way, you know more now than you did before you did the job.
