Wayback Wallet от WaybackDev

An extension that tracks prices on supported e-commerce websites like Amazon and Takealot. It quietly collects the title and price of items in the background while you browse.

When activating the plugin via its icon, you will be able to see whether the current price is higher or lower than previous visits.

All data is completely stored locally in your browser and is never sent to us or anywhere else.

On the settings page you can view a table of all visited products and their high-, low-, and last known prices.

You can also export the data to CSV.
