Zactr

Zactr analysis, right on the Amazon product page

The free Zactr Chrome extension adds a compact analysis strip to Amazon product pages — how the current price compares to recent deals, whether the product is climbing the bestseller charts, and how competitive the offer list is. Built from Zactr's daily marketplace observations.
