Automated Product Price Change Tracker
Tracks price changes on e-commerce websites via scheduled web scraping and sends email alerts for updates.
This n8n workflow automates monitoring of product prices on specified websites, ideal for e-commerce price tracking. It runs on a cron schedule (default 15 minutes), fetches pages via HTTP Request, extracts prices using HTML selectors, compares against stored data in a JSON file, and emails notifications on changes.
Key features include customizable watchers (URL, CSS selector, currency, slug) defined in a Function Item node, data persistence via Execute Command for file management, and HTML Extract for precise scraping. Prerequisites are basic HTML/JS knowledge and folder permissions for /data/kopacky.json.
Benefits: Saves time on manual checks, enables competitive pricing strategies, procurement alerts, and deal hunting. Use cases: Retailers tracking competitors, buyers monitoring deals, or businesses automating vendor price surveillance. Highly customizable for multiple sites.
New buyers can create an account from the cart to unlock a controlled $10 first-purchase credit on eligible orders of $25+.
