Price Watch 作者： Scrap Labs

Price Watch is for patient buyers. Open a product page, click the toolbar button, and the page's current price is saved as your baseline. Price Watch keeps watching that exact page; when it later shows a real drop below your baseline, a notification fires. There is no account, no dashboard, and nothing to configure. Built by Scrap Labs, the team behind DurablePicks, a publication that ranks gear by how it fails and what it costs per decade.
