I need a program that would take a list of ISBN numbers or UPC codes (hopefully, this will be selectable) and then look up each corresponding product on [url removed, login to view] and [url removed, login to view] and return the higest and lowest new prices and the highest and lowest used prices for each item. The data should be output in a format that can be read by Excel. The input list of ISBN or UPC codes could be in any format that Excel can save, or in a text file of one code per line.
The program would have to run on Windows XP or Windows 7. This could be either/or or both.
