God damnit. I didn't want to believe it. Tried to karate chop my keyboard but it lacked conviction

We reserve the right to deny requests for keys or revoke key requesting privileges for partners that are abusing them or disadvantaging Steam customers.
Occasionally it may make sense to offer your game in a bundle or subscription, timed at the right point in a game's life cycle. Keep in mind that the perceived price in the bundle/subscription should be a price you are willing to run the game at a standalone price or discount on Steam. Philosophically, you can think about it like any other discount: if you’re making an aggressive offer in one place, make it elsewhere too. We want to avoid a situation where customers get a worse offer on the Steam store, so feel free to reach out to us via the Developer Support tool if you want to talk through a specific scenario.
Please note that Steam keys cannot be sold on other sites unless the product is also available for purchase on Steam at no higher a price than is offered on any other service or website.
