Price Tracker Apps and Browser Extensions: Compare 5 Options for 2026

You buy a TV at a "sale" price, then watch it drop again a week later. Or you find out the "was" price was never real. A price tracker helps you avoid both by showing price history and alerting you when a price falls.

Holiday shopping raises the stakes. US shoppers spent $257.8 billion online from Nov. 1 to Dec. 31, 2025, according to Adobe, with electronics discounts peaking at 30.9%. That discount is measured off the listed price, which may not match a genuine prior price.

Below, you can compare five price trackers on store coverage, alerts, price history, cost and privacy. For more ways to cut costs, see our guide to the best money-saving apps for shopping.

BestMoney's editorial team compared five price trackers using each provider's official listings and help pages. Here's how they line up as of November 2026.

What Does Google Shopping and Chrome Price Tracking Offer?

Google's price insights label a price as low, typical or high and flag 30-day lows for US shoppers. Google notes the feature doesn't predict future prices.

Chrome's Shopping Insights add price history and price ranges across the web. Chrome's help page says tracking requires signing in to Chrome with your Google Account and syncing your history, and it works on trackable product pages.

What Does Keepa Offer Amazon Shoppers?

Keepa is an Amazon-only price tracker. Its Chrome Web Store listing says you can get notified when a product drops below your target price or returns to stock. You don't need an account to start tracking.

The Keepa iOS app is listed as free and includes a barcode scanner for checking Amazon prices in stores. For paid-plan pricing, check Keepa's site.

What Does PayPal Honey Droplist Offer?

PayPal Honey says Droplist works at select stores with no item limit, but tracked prices exclude shipping, tax and handling. It also can't guarantee a drop or hold an alerted price.

Alerts arrive by email or browser notification, according to PayPal. Honey's Chrome listing also discloses that merchants may pay it affiliate commissions.

Choose a price tracker by matching it to where you shop, the data you want, the access it needs and what happens after checkout.

Which Stores Do You Shop Most?

If you mostly shop on Amazon, Keepa and the Camelizer focus there. If you split purchases across retailers, look at Chrome price tracking, Honey Droplist or Capital One Shopping. Need a Walmart price tracker? Check whether the product page is trackable in Chrome or supported by Droplist.

Do You Want Price History, Alerts or Both?

Price history tells you whether a deal is real, and alerts tell you when to buy. Think of price history like a car's service records. You check them before you trust the sticker.

The FTC's Guides Against Deceptive Pricing say a "former price" should be genuine and offered regularly for a reasonably substantial period. An inflated price set only to advertise a big markdown is a false bargain. A price-history chart shows you whether that "was" price ever stuck.

What Permissions Does the Extension Ask For?

A price tracker extension needs some access to the pages you shop on to read prices. PayPal says Honey collects data to operate features such as price-drop alerts. Keepa's listing says its extension requests access only to keepa.com and Amazon domains.

Creators sued PayPal, alleging Honey replaced their affiliate IDs at checkout. A federal judge dismissed the first amended complaint in November 2025 with leave to amend. On June 22, 2026, the court denied PayPal's motion to dismiss the second amended complaint, so the case continues, though the claims remain unproven allegations.

In March 2025, Google announced Chrome Web Store affiliate rules requiring extensions to disclose affiliate programs. Before you install any tracker, read the permission prompt and the privacy policy.

What Happens If the Price Drops After You Buy?

It depends on the retailer, so pair alerts with its price-match window. Policies below are as of November 2026; check current terms before you buy.

Are price tracker extensions safe to use?

Safety depends on what an extension can access and how it uses your data. Before installing, review the permission prompt and privacy policy. The permissions section above covers what to look for.

Does Google have a price tracker?

Yes. Google Shopping's price insights show US shoppers whether a price is low, typical or high. Chrome can track prices on trackable product pages when you're signed in, with no separate extension needed.

Can I get money back if a price drops after I buy?

It depends on the retailer, and price matches are made on request. Best Buy and Target match their own lower prices within set windows, while Walmart doesn't price match Walmart.com purchases that later drop and Amazon says it doesn't offer price matching compensation.

A price tracker pays off when it matches how you shop. Keepa and the Camelizer focus on Amazon, while Google, Honey Droplist and Capital One Shopping reach more stores.

Use price history to judge whether a "sale" is real, and check permissions before you install. Then time your purchases around each retailer's price-match window so a later drop doesn't cost you.
