An even better deal

Regarding the previous edition of the thermodynamics book I "used" last year: Many students still use the 4th edition; it has a nicer cover (not all freaking orange like the 5th edition) and the interior coloured stuff is in deep red rather than red red. It goes for between $50-70 on the used book registry.

At the United Way garage sale event this year, there was a copy of this book lying around.

At $0.25, it's more than a steal to the point where I don't think there's a word for it.
