Amazon Web Services allows websites to have rich content and powerful capabilities using the following features:

Amazon.com - Detailed Product Information
The Amazon API provides complete details of each product and its pricing information from the Amazon catalog. This makes it easy for websites to display a product online with complete descriptions and features (e.g. a Jewelry store can obtain the 4C's of a diamond item that is being sold at Amazon!)

Amazon.com Images
The product image library at Amazon is definitely one of it's kind. There are millions of new images that are of high clarity. Using the Amazon API, you can display these images on your own website for any product that is available at Amazon. Even the newest images are available to you immediately!

Customer Reviews
You can even obtain all custom reviews for a product or, reviews written by a particular reviewer only! These reviews are available in standard HTML format which makes it very easy for you to display them in your own style within your website.

Extended Search
Amazon Affiliate Sites can create applications with complex search options. The same functionality as Amazon.com's "Advanced Search" is now available via the Amazon Web Services API which allows searching by numerous attributes, including brand, price, and category.

Remote Shopping Cart
Add the Amazon.com Shopping Cart functionality to your own Web site or application! This includes the "Save For Later" feature. So a visitor to your site can do all his/her shopping at Amazon without ever leaving your site and at the time of checkout is seamlessly transferred to Amazon.
