Amazon still shows a 1-2 month delay in shipping it, which is basically a pre-order. You can pre-order it from Bookpool for five bucks less. In general, Bookpool's prices are better than Amazon's, but they sell mostly technical books.
Factor in the shipping costs as well. Bookpool is starting to wake up and offers free shipping in the U.S. on orders over 40$, but last time I went to order a book, the shipping costs alone were 30.00$.
