I need a software being written that will crawl [url removed, login to view] (German Amazon website) for a given set of EAN codes (German version of UPC codes, the barcode printed on a product), and return several values:
number of offerings in new and used state
lowest price for each state
name of the lowest offering competitor for each state
The EAN codes should be imported from a plain .txt file.
The program should be developed in VB.net or C#.net (Visual Studio 2010) and it is required that I´ll receive the source code including full rights.
