You are absolutely right and we are aware of this as we calculated it through.
Pricing an OS project isn't easy and we will introduce scaled prices per submission e.g. 500-2.000 -> 0,02$, 2.000-10.000 -> 0,01$ and > 10.000 -> 0,005$ or so.
We just didnt want to make it too complicated early on.
That makes sense. All the best. I will definitely recommend Snoopforms to people I know. I generally self-host whenever I can and I will self-host this when I need this in future. I hope I can still pay one-time fee down the line when I need it/self-host to support the project. Thanks
