A few things about this.
It's expensive to print books and I did my best to drive the price as low as I can, but it comes in at $49 USD. That's not that expensive, I suppose, when it comes to print books like this one.
The main reason it's priced this high is because I needed color. Not quite picture book color, but something that would make my stellar drawings look stellar:
I think they look pretty good!
I trimmed a little here and there to get the book size to fit Blurb's required page limit (480 pages). It's exactly 459 pages in length, in case you're wondering.
As I mention, I opted for "Economy Color" paper. I wasn't sure how it would turn out, but it looks pretty damn good! Even the code samples print clearly and legibly.
I went with 6x9 "Trade Book", which is a bit smaller than normal hardcover books. It fits really well into a bag and looks fashionable too:
Can I Have [Discount/Ebook/Something]
I can't offer any discounts to existing owners of the book as the expense of printing this thing is... expensive. To be honest I would lose money and that's not fun.
Blurb is the seller, however, and they do put on sales from time to time. I wouldn't be surprised if they did something for Black Friday or Cyber Monday. If you want, you can check my twitterz and I'll tweet it out if they do.
Regarding the digital version: I don't have access to anyone's information, so there's simply no way to bundle this in. I'm trying to figure out a way to make this happen but so far I've had no luck.
