Amazon Price Tracker
A free price monitor that imports your Amazon orders from Gmail and watches for price drops so you can request an adjustment or time your next buy.
The Problem
You buy something on Amazon. A week later, the price drops. You never find out. Or worse, you find out months later when you happen to look at the listing again. Some people use browser extensions to track prices before they buy, but almost nobody monitors items after purchase. That is where the real savings are, especially on bigger ticket items that fluctuate regularly.
How It Works
- Auto-imports orders from Gmail by scanning your Amazon order confirmation emails and adding items automatically
- Tracks new and used/renewed prices on every item, since the used market sometimes drops faster
- Configurable alert thresholds per product or globally: percentage drop, dollar drop, or a specific target price
- Email alerts with the product name, old price, new price, percentage change, and a direct Amazon link
- Screenshot capture of the Amazon product page with every price check for your records
- Recall monitoring that scans CPSC and FDA databases for safety recalls on items you have purchased
- Price checks run every 2 to 4 hours on a randomized schedule to avoid detection
- Auto-update notifications when a newer version is available
Installation
On Windows, download the EXE from the latest release and double-click. On Mac, download the Python script and the launcher. Either way, the app installs all dependencies on first run. No manual pip commands, no virtual environments, no configuration files to edit. The setup wizard walks you through connecting your Gmail account using an App Password.
The app runs in your system tray and serves a local web dashboard where you can see all tracked items, price history, alert settings, and screenshots.
Privacy
This runs entirely on your computer. The only network connections are to Amazon.com (price checks), Gmail (importing orders and sending alerts), and CPSC/FDA (recall checks). Your purchase history and price data live in a local database. Nothing is uploaded to any cloud service.
If you travel frequently and want a similar monitoring tool for flights, the Delta Price Tracker follows the same self-hosted, privacy-first approach.
