price-tracker

What This Skill Does

The price-tracker skill is a powerful analytical tool designed for e-commerce professionals, arbitrageurs, and savvy shoppers. It connects to major retail platforms including Amazon, eBay, Walmart, and Best Buy to aggregate real-time pricing data. By monitoring these sites, the skill identifies significant price disparities, tracks historical trends over 90-day periods, and automatically calculates net profit margins after accounting for platform-specific fees (such as Amazon's 15% referral fee or eBay's final value fees). It transforms raw market data into actionable intelligence, allowing users to execute profitable flips or secure the lowest possible purchase prices through intelligent automation.

Installation

To integrate this tool into your environment, use the OpenClaw command-line interface. Ensure you have the necessary environment variables configured for marketplace API access. Execute the following in your terminal: clawhub install openclaw/skills/skills/michael-laffin/price-tracker. Once installed, you can verify connectivity by running a test comparison command using the provided scripts folder.

Use Cases

• Retail Arbitrage: Identify items undervalued on one platform to resell on another for a minimum 20% margin.
• Competitor Intelligence: Set persistent alerts to monitor when a competitor drops their price, allowing for dynamic pricing adjustments.
• Historical Purchasing: Analyze 30, 60, or 90-day price fluctuations to avoid buying at the peak of a cycle or during temporary price spikes.
• Stock Alerts: Automate inventory monitoring for high-demand goods that fluctuate in availability and cost.

Example Prompts

1. "Monitor the Sony WH-1000XM5 across all supported platforms and alert me if the price gap between Walmart and Amazon exceeds $40."
2. "Show me the 90-day price history for the Nintendo Switch OLED and suggest the optimal time to buy based on recent seasonal discounts."
3. "Set up a daily automated scan for all items in my 'Tech-Flip' spreadsheet, notifying me only if a 25% profit margin is achievable after all transaction fees."

Tips & Limitations

• Fee Accuracy: Ensure your account settings reflect your current seller tier, as platform fees may vary based on account type and membership level.
• Rate Limiting: Frequent polling can trigger anti-scraping protections on retail sites. We recommend setting alert frequencies to 'daily' for bulk lists to ensure reliability.
• Data Latency: While the tool provides near real-time data, there may be a slight lag between a retail site update and the reflected data in the tracker; always verify on the platform before executing high-value transactions.
