Wayback Wallet is a free Chrome extension designed to help users track product prices over time on various e-commerce platforms such as Amazon and Takealot. This tool operates in the background, collecting the title and price of items as users browse, allowing for easy comparisons of current prices with historical data.

When users activate the extension, they can quickly determine if the current price is higher or lower than previous visits. Additionally, all data is securely stored locally in the browser, ensuring user privacy. The settings page offers a comprehensive overview of visited products, displaying their historical high, low, and last known prices, with an option to export this data to CSV for further analysis.
