And Paizo has stated more than once that, although they like customers to buy from here (because Paizo gets a bigger cut that way), they encourage folks to buy their products wherever it is most convenient for the customer.
I have not cancelled my sub yet, but I also may take a look at that "Book Match" option on Amazon.
I have a question for anyone who has looked into the other digital book providers. Paizo was providing an ePub and a PDF of the books. Is the PDF available from any of the ebook sellers or is it only ePub/Mobi/[insert proprietary format here]? I was just starting to get into reading them as pdf's instead of as ePubs. If I can only get ePub going forward, then I'll survive.
