The Story
An avid tech enthusiast was tired of constantly checking prices on desired items, missing out on flash sales, and discovering purchases could have been cheaper if bought at a different time. They needed a system that could monitor prices 24/7 across multiple retailers, alert them instantly when prices dropped, and track price history to identify the best time to buy.
"I never miss a deal now. OpenClaw caught a 50% price drop at 3 AM and woke me up. Worth it."

🔧 How It Works
OpenClaw continuously monitors product prices across multiple retailers, tracks price history, and sends instant alerts when significant price drops occur.
1. Product Watchlist Setup
Created a watchlist of desired products with URLs from multiple retailers (Amazon, Best Buy, Walmart, etc.).
Stored product URLs, target prices, and notification preferences in a structured format for easy management.
2. Continuous Monitoring
OpenClaw checks prices every hour using browser automation and APIs, storing historical data.
Implemented a scheduling system that checks each product and records price, timestamp, and retailer.
3. Price Drop Detection
AI analyzes price history to detect significant drops and identifies genuine deals vs. fake sales.
Uses statistical analysis to distinguish real discounts from artificial price inflations followed by 'sales'.
4. Smart Alerts
Instant notifications are sent when prices drop below target or reach historical lows.
Delivers alerts via push notifications, SMS, or email with price comparison charts and quick purchase links.
