I need a web scraper script built in whatever language is your preference preferably something that can be easily executed in a browser. But if it is cheaper, faster, and easier to build something outside the web browser I am open to those ideas. This scraper script will monitor all of our amazon products and make sure we have the lowest price on the product and are the featured 'buybox' merchant. If those conditions are not met it will be compiled into a list and then emailed to me, telling me which product, our price+shipping, the current lowest price+shipping, the price difference, and whether we are winning the buy box and who the competitor is. I don't need a cron script that automatically does this, the products we sell aren't highly competitive with hourly changing prices so it won't be necessary to be constantly running this script. Preferably I would like to run the script at my leisure when I want to check out our pricing. When you bid please list our previous experience in scraping, the time it will take, and the milestone required.
