For this mashup we will be creating a new Rails application to demonstrate how you can integrate this feature into your website. The Rails application will have a left-hand sidebar that shows your book, its details, and a list of similar books. The sidebar also shows the most recent sales rank from Amazon and a list of historical sales ranking for the past 10 days, displayed in a sparkline. Your visitors can also view comments and ratings from other readers posted on Amazon.com.

This mashup also enables you to create a remote shopping cart at Amazon.com to let your visitors buy directly through you. At the same time, it allows you to earn some extra money by being an Amazon Associate and referring other similar books to your visitors and allowing your visitors to add them to the remote shopping cart. When your visitors are ready to buy, the mashup will redirect them to Amazon.com for checkout and payment.

This is the sequence of actions we will take to create this mashup...
