This n8n workflow automates the process of monitoring product prices from multiple online sources, saving the data locally, and sending notifications when prices change. It operates on a scheduled basis every 15 minutes, fetches webpage content using specified CSS selectors, extracts the current prices, and compares them with previously stored values. If a price drops or is updated, it updates the saved data and sends email alerts to notify the user of the changes. The workflow integrates web scraping, local file storage, and email notifications, offering a practical solution for e-commerce managers and price-sensitive shoppers interested in real-time price tracking and alerts.
