Updated October 2026 · By Sophia · How we put this together: we compared each tool’s features, coverage, cost and privacy trade-offs using the tools’ own documentation, Google’s help pages, independent reviews and public reporting. No brand paid to be included, and there are no affiliate links in this article.
Quick answer: For Amazon, use Keepa if you want the most detail right on the product page, or CamelCamelCamel if you just want free email alerts. For everything that isn’t Amazon, use Google’s built-in price tracking. Treat coupon extensions like Honey as optional extras, not price trackers.
A price tracker does one simple, powerful thing: it shows you what a product has actually cost over time. That’s the fastest way to tell a real deal from a dressed-up regular price, especially in the run-up to Black Friday.
There are dozens of these tools. Most shoppers only need one or two. Here’s how the main options compare, who each is best for, and the catches nobody puts in the app-store description.
Price tracker comparison at a glance
| Tool | Best for | Stores covered | Cost | Price history | Alerts |
|---|---|---|---|---|---|
| Keepa | Detailed Amazon charts on the product page | Amazon (many countries) | Free for shoppers; paid Pro plan for sellers | Yes, long and detailed | Yes |
| CamelCamelCamel | Simple, free Amazon alerts | Amazon (US, UK, CA, DE, FR, JP and more) | Free | Yes | |
| Google price tracking | Comparing many stores at once | Most big online retailers | Free | Up to ~90 days | Email and push |
| Honey (PayPal) | Auto-trying coupon codes | Thousands of stores | Free | Limited | Droplist |
Keepa: best for serious Amazon shoppers
Keepa is the tool I’d install first if most of your shopping happens on Amazon. Once its browser extension is installed, a price-history chart appears directly under the product on the Amazon page. You don’t have to copy links anywhere.
What it does well:
- Separate lines for Amazon’s own price, third-party new offers and used offers, so you can see who’s actually discounting.
- Price and back-in-stock alerts, on the free plan.
- A gap in the chart shows when the item was out of stock. That’s useful for spotting “deals” that only appear when supply is low.
The catch: the charts can feel busy at first, with color-coded lines for each price type. And the paid Pro plan (around €29 a month, according to RevenueGeeks) is built for Amazon sellers. Regular shoppers don’t need it.
Best for: anyone who buys electronics, home goods or gifts on Amazon more than a few times a year.
CamelCamelCamel: best free, no-fuss Amazon alerts
CamelCamelCamel is the “set it and forget it” option. Paste an Amazon link, pick the price you’re willing to pay, and it emails you when the price drops to that level. It’s free and paid for by Amazon affiliate commissions. Its companion extension, the Camelizer, shows the same chart without leaving Amazon.
What it does well: clear three-month, six-month, one-year and all-time charts; the lowest, highest and average price at a glance; and multiple alerts per product.
The catch: it covers Amazon only, and there’s no mobile app. Its history only begins when it started tracking that product, so very new listings have thin charts.
Best for: people who want one email when the price is right, and nothing else.
Google price tracking: best for comparing every store
Here’s the tool most people already have and never use. Search a product on Google and you’ll often see a price-insights box with the typical price range for that item. On desktop Chrome, a “Shopping insights” label appears in the address bar on many product pages. Clicking it shows the typical price and a history graph covering up to the last 90 days. (Google)
To get alerts, tap the bell or “Track price” option on a product in Google Search, or use the price-tracking toggle in Chrome’s side panel. Google then emails or notifies you when the price drops at retailers across the web.
The catch: about 90 days of history is shorter than Keepa or CamelCamelCamel, and not every product or store shows insights.
Best for: anything you might buy from Walmart, Target, Best Buy or a brand’s own site.
Honey: a coupon tool, and what you should know before installing it
Honey, owned by PayPal, is mainly a coupon finder. At checkout it tries available promo codes for you. It also has a “Droplist” for price alerts, but that isn’t its strength.
Honey has also had a rough couple of years. In December 2024 a widely shared investigation alleged that it replaced other creators’ affiliate links at checkout, and that partner stores could limit which codes it showed. Class-action lawsuits followed. In March 2025, Google changed Chrome Web Store rules to stop extensions from claiming affiliate commissions when they don’t give users a discount, and Honey updated its extension. The extension reportedly lost millions of users in the months after. (Background and timeline)
My take: Honey can still save you a few dollars on a code you’d never find yourself. But it doesn’t tell you whether the price is good to begin with. If you use it, pair it with a real price tracker, and don’t assume the codes it shows are the best ones available.
Which price tracker should you use?
- “I mostly buy on Amazon.” Use Keepa, and add CamelCamelCamel alerts for big-ticket items. Pair them with the tricks in our Amazon Prime shopping guide.
- “I shop everywhere.” Use Google price tracking, plus Keepa for Amazon.
- “I don’t want any extensions.” Use the CamelCamelCamel website and Google Search price insights. Both work in a normal browser tab.
- “I want coupon codes too.” Try a coupon tool if you like, but always check the price history first.
How to read a price-history chart in 30 seconds
- Find the lowest point in the last three to six months. That’s your realistic target price.
- Look for a pattern. If the price dips every few weeks, you can wait for the next dip.
- Check for a spike before the sale. A price that jumped up a week before a “discount” is a classic trick.
- Compare the seller line. On Amazon, make sure the low price is from Amazon or a well-reviewed seller, not a brand-new third-party account.

Price tracker FAQs
Is Keepa or CamelCamelCamel better?
Keepa is better if you want detailed charts on the Amazon page itself and back-in-stock alerts. CamelCamelCamel is better if you want a simple website and free email alerts with nothing extra. Both are free for shoppers, and plenty of people use both.
Can I track prices at Walmart, Target or Best Buy?
Yes. Google’s price tracking covers most large US retailers. Search the exact product, open its shopping result, and turn on price tracking. You’ll get an email or notification when the price drops.
Are price tracker extensions safe?
Well-known price-history tools are generally safe, but any extension can see some of your browsing activity. Install only what you’ll actually use, read the permissions it asks for, and remove extensions you’ve stopped using.
Do price trackers work on Black Friday?
Yes, and that’s when they’re most useful. Set alerts in early November with your target price. When a “Black Friday price” appears, the chart shows instantly whether it’s a genuine low or a price you’ve seen many times before.
Install one, set three alerts, and let the robots watch prices while you get on with your life. — Sophia
