Well, if they get the money they're asking for this book they're a VERY GOOD bookseller, and I'll send them a cookie.

Today, in the high-priced book category we have Amazon's SDSU_Books.
I would assume they were South Dakota State University, but since they say they ship from California, probably not. The university's bookstore would probably have more than the 4 feedback they have as well.

Here's the book:

Money, Banking and Financial Markets (Paperback) by Stephen G. Cecchetti ‹ Return to product information

..

And here's their listing:

$87,564,320,112.99 + $3.99shipping

Used - Very Good

Seller: SDSU_Books Seller Rating:100% positive. (4 total ratings) In Stock. Expedited shipping available. International & domestic shipping rates and return policy. If you read this book, you'll be able to afford the price! Ships from CA

Notice the low, low price of $87,564,320,112.99 and $3.99 in shipping. You'd think they'd thrown in the shipping for free at that price, but maybe Amazon won't let them.

There is another problem with this listing, but it's more Amazon's fault than theirs.
The book in question is a McGraw Hill international edition. If you blow up the picture of the book by clicking on it at its Amazon page, you'll notice that it says, "This International Student Edition is for use outside of the U.S."
Amazon shouldn't have a catalog page for items like this, and has banned third-party sellers in the past for listing these. The look of the page leads me to believe that Amazon, not a third-party seller created the page. It's got a bunch of reviews, and they're not from yesterday, so this listing has been around for a while.
Here's a link to the product page for this item.
