Query: Book's OK, Amazon's price off by $10

The book has a bunch of tips, roughly 2 per page, like the other books in the series. There's a mix of 3 kinds of tips -- ones that are common to other programs, like Illustrator and Photoshop, ones that are unique to InDesign, but either fairly obvious, or just uninteresting, and ones that are unique and non-obvious. There are enough of the latter to warrant buying the book, if you want to learn the shortcuts that make you efficient with the program. The CS series of programs no longer come with manuals by default, and the manuals that are available from Adobe by special order are much thinner than in past releases. So we're going to need books like this to reveal the shortcuts, especially those that don't have corresponding menu items!Note, however, that the current price Amazon is listing, $39.99, is off by $10, since the actual retail price of the book is only $29.99.
