Well, after lunch when I went to pay for it, somehow the ebook was $10. I removed the book and was able to get the ebook for $10. As others have said, while it's a nice price, I like to see the author get rewarded for their effort, so I'll probably do the "upgrade to print". I also picked Paypal because I'm not sure if this is some clever dynamic pricing/optimization engine or if the site is buggy!
