How do I know which eBooks are pre-order items as opposed to eBooks that are available for immediate download?
Pre-order eBooks are clearly marked in several different ways to distinguish them from eBooks that are immediately available for download. For one thing, there is a note like this next to the title in your cart and in all search/browse/informational pages that describe the eBook: [PRE-ORDER ONLY: Available: Nov 04, 2003] Also, instead of an “Add to Cart” button on the right side of the screen, there is a “Pre-order this eBook” button to make it clear you are adding a pre-ordered item to your cart.
