Apologies if this has come up before, but would it be possible to update the app so that a purchase price of 0 is recognized as Free instead of the field being emptied on save if 0.00 is entered? Or is this already supported and I’m doing something wrong?
This is on our feature request list, and will likely make it to the apps at some point, but right now it’s not possible (you didn’t miss anything).
You could perhaps use the Tags field to mark the book as “Free” if you want to somehow “use” this now.
With my free books I’ve just entered the price as .01, so I can tell which books were free.
