Hi,
I have a lot of experience with data mining / scraping and have such developed many scripts which can collect a varied amount of data from amazon, some of which are the following.
I have wrote a script which already collect Amazon Reviews, taking all the meta data long with the review body text its self, (Asin, ReviewId, AuthorName, AuthorId, DateOfReview, ReviewTitle, ReviewContent, ImageList, Useful, TotalComments, RatingScore, ProductDescription, Purchased)
I've wrote a crawler for dropshopping, basically it takes the top 100 Asins for every sub category, and outputs the following (Asin, Title, Price, Seller ( if Prime ), which can then be uploaded using eBay/amazon drop shipping software.
I have wrote another script which monitors the offers/deals page on dvd's/blurays, it can work out which offers are on a multi buy offer or not, and them which are it then can work out its price based on using the offer and start collecting all the Asins, Title's under that visiting page after page.
The software i have created to allow me to do this is based around a framework i have developed over a few years, which allows me to data mine on a mass scale, which sits on a cluster of machines and uses multiple ip address's as well as code i wrote to deal with amazons captcha which prevents or hinders data mining for most.
the price is based on more information being provided and agreed upon.
