See a product's Amazon price history before you buy.
// WHAT IT'S FOR
Keepa shows charts of Amazon product price history and alerts you when a price drops. Search for the product on its site, or install the browser extension, which adds the chart right on the Amazon page. Use it to check whether a sale price is real, or to buy inventory when it's cheaper.
