Shoppers often miss out on better deals because they’re unaware of price changes on Amazon.
Build a browser extension that tracks Amazon prices and alerts users when they increase, suggesting alternative retailers.
Users would pay for premium features like price history charts and alerts for specific products.
Start with basic price tracking and alerts, then add integrations with other e-commerce platforms.
The biggest risk is Amazon blocking the extension, but focusing on user privacy and transparency could mitigate this.
