I've set up my POD, now what?

My cover and internal pages have been approved, but I don’t see an option to turn it on or make it available to the public to purchase. Should I also be able to set my own price? I’m probably missing something simple so any help is appreciated.

You need to add the book to one (or more) of your pricing tiers, just like with digital files.

Yup, it was something as simple as that. Thanks!
