BTW--for what it's worth, very few of the websites, that I've checked out, with open source books, price-match at Amazon. Of course, my experience may not be great enough to make generalizations. Too, by the very nature of open source, those books are offered only in digital form. When you go over to Amazon, usually (again, if my experience is any indication) there isn't even a digital version available of the title--only (a) dead-tree version(s). It doesn't quite work to price-match a physical book at Amazon for a digital one elsewhere. That's like comparing apples with oranges.
