BoB was kind enough to offer me a 50% store credit for the Narnia books. I suppose that's better than nothing.
Basically in the email they were trying to explain how much of a headache the whole Adobe Digital Editions, PDF and EPUB thing was causing. In their wisdom (BoB) they decided that calling the EPUB and the PDF format just Adobe Digital Edition would keep the confusion down...

. I wonder why publishers are even choosing the PDF format over the EPUB anyway?
