The Best Shopping Extensions for Saving Money

The most useful shopping extensions fall into three groups: coupon finders (PayPal Honey, Capital One Shopping, DontPayFull), cashback (Rakuten, Ibotta) and Amazon price trackers (Keepa, the Camelizer). Install one from each group rather than several that do the same job, and only from your browser's official store.

1. PayPal Honey

Honey, now part of PayPal, searches for coupon codes at checkout on more than 30,000 sites and applies one that works. Honey Gold earns rewards at some stores, which you can redeem for gift cards. It runs in Chrome, Safari, Firefox, Edge and Opera.

Good to know: In December 2024 Honey was accused of replacing creators' affiliate links and of letting partner stores limit which codes it shows. After Google changed its Chrome Web Store rules in March 2025, Honey stopped claiming affiliate commissions when it doesn't apply a discount.

2. The Camelizer

The Camelizer, from camelcamelcamel, shows an Amazon product's price history right on the product page and can email you when the price drops to a target you set.

3. Rakuten

Rakuten, formerly Ebates, pays cash back when you shop at partner stores through it, and its extension reminds you to activate cash back when you land on a participating site.

4. CNET Shopping (formerly InvisibleHand)

InvisibleHand's website now redirects to CNET Shopping, the price-comparison extension that took its place. It shows when the item you're viewing is cheaper at another store.

5. Keepa

Keepa tracks price history for products on Amazon's marketplaces and sends price-drop alerts. It overlaps with the Camelizer, so most shoppers only need one of the two.

6. Ibotta

Ibotta pays cash back on purchases made through its app and in stores, including groceries.

7. DontPayFull

The DontPayFull extension finds coupon codes for the store you're on and applies them at checkout.

Good to know: Two extensions that both add affiliate links can cancel each other, so check your cashback account after the order.

8. Capital One Shopping

The Capital One Shopping extension automatically applies coupon codes at checkout, alerts you when prices drop on products you've viewed, and earns Shopping Rewards at partner stores.

FAQ

Why should I use shopping extensions?

They find coupon codes, cash back and lower prices elsewhere while you shop, so you don't have to search for them yourself.

Are these extensions safe to use?

Install only from the official browser stores, read recent reviews, and check the permissions an extension asks for. Popular tools still change or close: Mozilla shut down Fakespot, the review checker, on July 1, 2025.

Can I use multiple shopping extensions at once?

Yes, you can. However, having too many active extensions might slow down your browser. It's advisable to enable only those extensions that you use frequently and disable others when not in use.

Will these extensions save money on every purchase?

While these extensions significantly enhance the chances of securing a better deal, no tool can guarantee savings on every single purchase. Factors like regional pricing, limited-time offers, or stock availability can influence outcomes.

How do these extensions make money?

Most earn affiliate commissions from stores when you buy through their links or after they apply a code. Since March 2025, Chrome Web Store rules bar extensions from claiming a commission when they don't give you a discount.

Should I use an extension that isn't in an official browser store?

It's safer not to. Extensions outside the official stores skip their review, and shopping extensions can see the pages you visit. If you try one anyway, check its permissions and remove it if it asks for more than it needs.

How to choose

Pick extensions that match how you shop. Here's what to check:

1. Utility: Does the extension offer features you'll regularly use?
2. Compatibility: Some extensions work better with specific sites. Match your favorites.
3. Trustworthiness: Read recent reviews and search for news about the extension before you install it.
4. Overlap: Some extensions offer similar features. For instance, both CamelCamelCamel and Keepa focus on Amazon. Choose the one that resonates with you.
5. Extension Management: Browsers have a limited memory. Too many active extensions can slow it down. Use extensions like Extensity to quickly enable/disable extensions.
6. Regular Cleanup: Every few months, audit your extensions. Remove those you don't use to keep your browser snappy.
7. Read Permissions: Extensions request certain permissions. Always review these. If an extension requests more permissions than it needs, think twice before installing.
