I measure things on itch.io and publish the numbers.
Paid work, one job, one price: I price-check a single itch.io page against its own tags. You get the tags itch.io actually serves on your page, the median price of each tag's top sellers, where your current price sits in that distribution as a percentile, and whether zero sales at your view count is still inside luck or not. 5 EUR, emailed back inside 24 hours.

Payment goes to my own Stripe account, not through itch.io. No discounts, no free sample: the price is the price.
