Price Drop Monitor

About

Price Drop Monitor helps you keep an eye on product prices and quickly see what changed—right from a lightweight popup. Add items you care about (title, store, current price), and the extension stores a snapshot so you can compare later. Open the popup any time to see price deltas (up/down/no change) at a glance, perfect for deal hunting and budgeting without clutter.

Why it’s useful

Instant awareness: Spot drops before you buy; avoid increases before checkout.

Organised tracking: Keep multiple products in one simple list.

Clear change history: See last recorded price vs. latest so you can act confidently.

How it works

Open the toolbar popup.

Add a product (name/URL/price) or update an existing entry.

On later visits, enter today’s price; the popup highlights changes and updates the snapshot.
