If you really need to buy a physical copy of this book, get it on Amazon. It is cheaper and has more/better shipping options. Buy the PDF here if you want that.
I pre-ordered this book, and not only was it cheaper on Amazon, I would have acquired the book by now. Everything about the value of purchasing it here has been worse than what I would have gotten through the Paizo Amazon store. If at least one thing had been better, I would have gladly accepted the extra cost to support Paizo, but my loyalty has been met with indifference, and I can't recommend my decision to anyone else.
