Here is the quick summary which I think is exactly what I want
* Keyword search which will search for DVD and BOOK in Amazon UK, Amazon DE etc as selected in a dropdown and list 100 results
This 100 result can be refined by "publication date"
And the result will show the following data in output
title ¦ date ¦ isbn/EAN ¦ price lowest ¦ price retail ¦ publication date
* The price lowest should take into account shipping if prime not available.
