A request for this board specifically: when you ask about pricing, bring the numbers.
Not "how should I price this" — that cannot be answered. Instead: what it costs you to make, what the platform takes, what you currently charge, and what you think is wrong with that. Then people can actually help.
Round numbers are fine. Nobody needs your real revenue. But "my cost is about $4 and I charge $12" gets you a useful answer, and "what should I charge?" gets you six guesses.
