From now on, I’m only selling books direct.
I should have done this earlier, but procrastination won out. What turned things around now, was Apple’s insistence on the requirement that I sell via EU-specific stores to reach EU customers, and those stores were about to require me to publish my home address and phone number.
Also the whole “Apple takes 30% of the cover price” thing, and the “Apple publisher tools have become garbage” thing.
So, we out.
