Amazon Flexible Payment Service , A Series of Blog Posts

I am planning to write a series of blog posts detailing my experience
with Amazon's Flexible Payment Service.(http://aws.amazon.com/fps/) Amazon's offering competes with PayPal, Google Checkout, http://www.authorize.net/, and other payment api's.

I am creating a series of blogs because Amazon's FPS API is a large offering and a single blog post would only skim the surface.
Series topics will include:

Overview of Amazon FPS,
Setting up your Environment/Creating your FPS account,
Creating Payment Instructions,
Creating a database to store submitted transactions,
Using Co-Branded UI,
Creating Pay Request,
Pull Method - Create a Job to Polling Amazon's FPS Service for successful Pay Request,
Push Method - Use Amazon Notifications to get Status of Pay Requests
