Part five: watch a shop's prices, and get an alert when they drop. Open the page you want to watch. In step two, set repeat to every day, and say how big a drop you care about. Ten percent here. Scrape once. The page is now watched, and it runs again by itself while Chrome is open. Your watched pages are listed in step three, with the next run. Up to ten pages. Each new run marks and counts what moved: cheaper, dearer, and new products. And when a price falls by your percentage, a notification names the product. Web Product Scraper. Free on the Chrome Web Store.
