Ebay Price Scraper

I would import a list of ISBN's that would be in excel in a csv. I would want the program to return the cheapest 'buy it now' price including shipping for both new and used (separately) on [login to view URL], so I would have two columns, cheapest new, cheapest used. If the book isn't available on ebay I would want it to return a result such as 'not available'. I would want the results to return in an excel spreadsheet so I can manipulate the figures further.
