Review: Someone's paying for it, even if you're not.

That's the main idea behind "Cheap: The High Cost of Discount Culture," a new book by Ellen Ruppel Shell.

Shell admits right off the bat that she's a bargain hunter. The problem, she says, is what we consider bargains may actually be hurting the environment, our expectations and employees around the world.

By now, most people understand the difference between between cheap and being frugal. The former looks only at price. The latter also considers quality. Shell uses examples like Ikea and outlet stores to show how looking nearly exclusively at price tags can dilute brands and affect buying habits.

But whether you label yourself cheap, frugal or just plain thrifty, do what I did if you want to read this book. Get it at the library.
