"It was something I could probably code in a weekend or so"
I think that's a key point. You look at the solution, think about the effort required for the value it gives you, and $10 feels about right.
For someone who can't produce it themselves, the value is usually much higher - and related to the size of the problem solved, not the amount of effort required to solve it. I don't know whether that applies in your specific case (for example, selling a 'one use' service on a subscription basis may not be the best plan), but it's a useful general point I thought of reading your comment.
