Oh! This one has been asked quite a few times over the last year!
Joy sent us the most recent inquiry… and I’m working on getting an answer (but I *think* we may have it, below).
She asks:
“Hi Maryse, I buy most of my books from Amazon.
I noticed that books cost more sometimes on iBooks and Google Books. What I have learned from browsing iBooks is that more pre-orders are available on iBooks than are on Amazon.
I realize that some are exclusives and that you can also get novella exclusives for some book series such as Pucked. For example, Tijan’s Anti-Stepbrother was available for pre-order as a paperback but did not go live as an ebook until it’s release date on Amazon when it was available as an ebook pre-order on iBooks.
