Data mining software

I need a piece of software that will check the buyback prices of books on textbooks.com. Essentially this is automated data collection. The software would take ISBN's from a list and check their buyback prices. The ISBN's are entered at this URL, in the "Sell Your Books" field: [login to view URL] Up to 25 can be entered at a time, so that would need to be considered seeing as I need an application that would be able to get the buyback prices for several thousand ISBN's in a short time span. There are ISBN's that will have no buyback value, and those need to be recorded as well. The output would ideally be an Excel output that has the ISBN and the buyback value, preferably in the same order that they were entered. Here is a sample list of ISBN's that you can use: [login to view URL] If you have any other questions about the project feel free to contact me. The most important part of this project is that the buyback prices can be collected quickly and efficiently, even with an input of several thousand ISBN's.
