Why You Need a Price Tracker
Online prices are not static. On large marketplaces like Amazon, prices can change multiple times per day based on algorithms, competitor activity, and demand signals. A product listed at $89 today may have sold for $54 three weeks ago — and will likely drop again. Without price history data, you're flying blind.
Price tracking tools solve this problem by logging price changes over time and alerting you when an item hits a target price you set. They're free, easy to use, and can save you real money on purchases you were going to make anyway.
The Best Free Price Tracking Tools
1. CamelCamelCamel (Amazon)
CamelCamelCamel is the gold standard for Amazon price tracking. Paste any Amazon product URL into the site and you'll instantly see a chart of its price history — including third-party seller prices and Amazon's own price over months or years.
Key features:
- Full price history charts for any Amazon product
- Price drop alerts via email when a product hits your target
- Free browser extension (The Camelizer) that shows history inline on Amazon pages
- Tracks Amazon price, third-party new, and used prices separately
Before buying anything on Amazon over ~$25, checking CamelCamelCamel takes 30 seconds and can tell you whether today's "deal" is genuinely good or if the item regularly sells for less.
2. Honey (Browser Extension)
Honey, owned by PayPal, serves two functions: it automatically tests available coupon codes at checkout, and it includes a "Droplist" feature where you add items and receive alerts when their price drops. It works across many retailers beyond Amazon.
Best used for: Auto-applying coupon codes and monitoring wishlists across multiple stores.
3. Capital One Shopping
This free browser extension compares prices across retailers in real time when you're browsing a product. It also notifies you of price drops on tracked items and can surface lower prices at competitors automatically. No Capital One account required.
4. Google Shopping Alerts
Google's Shopping tab aggregates prices from thousands of retailers. While it doesn't offer dedicated price drop alerts, combining it with a Google Alert for specific product names can help you catch deals. It's also excellent for initial price comparisons before you decide where to buy.
5. Keepa (Amazon)
Keepa is a more data-rich alternative to CamelCamelCamel for power users. It shows detailed pricing charts, tracks Lightning Deals history, monitors availability, and has a browser extension that overlays data directly on Amazon listings. The free tier is comprehensive; a paid tier adds additional data exports.
How to Build a Simple Price Tracking Workflow
- Identify the item you want to buy and find its Amazon or retailer listing.
- Check CamelCamelCamel (for Amazon) to see the historical price range.
- Set a price alert at or slightly below the historical average price.
- Add it to Honey's Droplist if you shop across multiple retailers.
- Wait for the alert — then buy with confidence knowing you're getting a fair price.
What Price Trackers Can't Tell You
Price history is useful but not the whole picture. A few limitations to keep in mind:
- Stock levels: An item at a great price is worthless if it's out of stock. Some trackers show availability history, but popular items move fast.
- Quality changes: Products can be reformulated or downgraded while keeping the same listing. Read recent reviews alongside price data.
- New vs. used: Make sure you're comparing like-for-like when looking at price history that includes third-party sellers.
Final Word
Price tracking is one of the highest-return, lowest-effort habits a smart shopper can build. Install CamelCamelCamel's browser extension and Honey today — they take minutes to set up and will pay for themselves (in savings) the first time you catch a genuine price drop on something you wanted.
