Just a heads up, you might be better off ordering this directly from BitMap Books, the creators.

I contributed to the Kickstarter for this (and the previous NES one, which is excellent) and here is some info from the backer page:
Amazon.com update
So the saga continues. Turns out after multiple calls to the US and emails, that Amazon can legally list whatever they like at whatever price they like. I've had several emails from distressed backers that Amazon are selling the book at a lesser price so soon after the Kickstarter. I'll say this again, just so it's 100% clear:
Amazon.com / Amazon.de / Amazon.jp will NOT be getting stock on this book. I personally control exactly where my stock goes and for books to go into Amazon you have to be a registered seller (which I'm not) or have an agent who is. So, these sites cannot fulfil the order they're taking so just ignore the listings. I very rarely discount my books and I would never be stupid to discount by almost 50% before it's even released! I would never disrespect my backers like that.
