BTW
You lose 10% from the Marketplace listing price - 5% to Adobe and another 5% to Fastspring
Another downside of Marketplace - you have no idea how many people even downloaded your plugins. Or installed for that matter. Especially applies for free versions, because for paid you can at least see on Fastspring how many purchaced. But even there I didn’t see any filters to split stats by plugin for longer periods of time. Adobe currently does not provide any stats, although, to be fair, during one of the recent meet-ups, they promised something for the end of the year in that regard
