I need an application that can retrieve pricing data using the new Amazon MWS API (this is not the old Product Advertising API). I need you to be knowledgeable of this API, as I do now know it very well.
The application will need to accept a text file of ASINs, call a function(s) using the Amazon MWS API, and return and present the data. The data will need to be presented in a GUI grid output. We will discuss the specific data and output layout during development.
