We've got a pre-order going here that includes a 4-week meal plan and a bunch of other goodies, and supports us. Amazon also has the book, and they're selling it significantly cheaper than we are -- because they can. (We don't feel like it's fair to undercut every other retailer who might carry the book by offering it for less than retail. That said, we're happy for you to buy the book wherever you'd like.)
If you're new to 'Well Fed,' check out the 'All 3 Books' deal in our shop. That'll get you about 500 paleo recipes for $45 (plus the electronic copies, the meal plan, etc).
Edited to add point about 'buy the book where you'd like.' Because truth.
