Thanks for giving it a playthrough and your thoughts, I appreciate it. The artifact has a description, though I don't blame you it's easy to miss in that garbage dump of a UI. The idea is that it counters the customer patience drain, but it in return you have to keep on activating it.
it seems like what i was selling was not tied to the economy
What's sold is tied to the economy, it isn't very apparent since I haven't added the ability to view an item's details like what category it's in.
I'm not so sold on allowing a mode of selling with only markup, or being able to cut to a certain % markup automatically. Though I think a decent compromise would be to add button shortcuts to up or lower the cents by 25.
