This is what I got from them:
"Thank you for writing to us at Amazon.com.
I truly understand your concern. Please allow me to assist you in this regard.
I've checked our web site and can confirm that the price of the item is $12.95.
There are several million items listed on our web site, some of which have never been ordered from us and may not have been ordered by any retailer for quite a while. This makes it impossible for us to check the price of every item on a regular basis. We rely on the data provided to us by our suppliers for any updates on the web site.
Unfortunately, no matter how frequently we update the web site, we can only make the changes if our suppliers have made them known. We also use data from other sources for web site updates, but occasionally this information is out-of-date or incorrect.
We make every effort to keep abreast of the changes in the status of items, and we feel that having an online computerized catalog allows us to update it more regularly.
We verify prices as part of our shipping procedures. If an item's correct price is lower than our stated price, we charge the lower amount and ship you the item. If an item's correct price is higher than our stated price, we will, at our discretion, either contact you for instructions before shipping or cancel your order and notify you of such cancellation.
Further, "World Atlas of Golf: The Greatest Courses and How They are Played (Hardcover)" hasn't shipped because it has yet to be released. As listed on our site, it's currently scheduled to be released on November 4, 2008.
As soon as the item has been released, we'll be able to ship it to you. As per our standard policy, we'll not charge you until the items are ready to be shipped.
