Spot on. So here's the problem: initially we wanted to just put the print-ready files on the website. But then — once we got more experience with physical printing — we've learned that it's not so simple, because there are several moving parameters (like bleed sizes, spine sizes, etc). As such, for now unfortunately you still have to email us with the parameters you need, so we can generate a PDF set for you. But in the future we want to just generate all possible sets and put them out there (all in due time).
