@kdfrawg I don’t really know what price you should set. The ranges you suggested sound reasonable. I thought the hardback price seemed high, then remembered it’s in dollars, not pounds, so that brings it down a bit.
For myself, I don’t buy books from Apple because of their lack of portability & I like to use somewhere other than Amazon if possible, to discourage their stranglehold, but I do buy from Amazon if I can’t find the book I want anywhere else.
Now can I read it?
