Monitor Amazon listing changes locally, including price, BSR, rating, title, image, and coupons. Amazon Tip is a lightweight local listing monitor for Amazon.com. Open an Amazon product page and add it to your monitor list. Amazon Tip saves a local snapshot and helps you track changes to price, Best Sellers Rank (BSR), rating and coupon information. You can review all monitored products from the extension popup, inspect a product's change history, or check the whole list on demand.
rating_count is the Chrome Web Store ratings count, not a written-review count.
