Everything in this book is pretty common sense, except for a couple of things that they really don't go into detail over. For example, they advice you to always look over the plans before you have a carpet installed - but never actually tell you why. So, if I were indeed to follow that advice I'd ask to look at the plans and then what? It will magically cost me less to install the carpet? I'd have no idea what I'm looking at. Their advice on shopping for cars was somewhat nutty too. As for the rest, like I said: common sense. Anyone who's even attempted to be frugal will probably feel like they wasted their time reading this book (and time is money, people!). If you have no clue where to start saving money, this book might be for you.
