Edited by other Updated Nov 13, 2025 Driven by the pursuit of a great deal, you’ve downloaded bar code scanning apps on your phone and clipped coupons from your local newspaper. But even you — a savvy deal seeker — may not know that your computer can replace both of those money-saving activities. Browser extensions are plug-ins you can download on web browsers like Chrome or Safari, and these tools can do your bargain-hunting homework for you. These are our picks for seven of the best browser extensions for online shopping. Each coupon finder covered is available for Chrome and other popular desktop web browsers.

1. PayPal Honey

PayPal Honey is a household name when it comes to browser add-ons that automatically find coupon codes at online retailers, and for good reason. It works! Rather than open a separate tab to search for coupons and sales from deal aggregator sites, simply shop as usual and let Honey work in the background. If Honey finds coupons, you can easily apply them at checkout. The Honey browser extension also promises to compare seller prices at Amazon. Additionally, Honey members can earn cash back on their eligible purchases through a rewards program, now called PayPal Rewards. Simply activate rewards while shopping, complete a transaction and earn a percentage back at eligible retailers. » MORE: What to know about cash-back shopping sites » MORE:

2. Rakuten Cash Back

Shopping rewards website Rakuten has a browser extension that members can use to activate cash back directly at store sites (rather than clicking through from the Rakuten portal first) and automatically apply coupon codes at checkout. Rakuten has rotating offers of various cash-back percentages from a wide selection of retailers, so you can compare exactly how much you’ll get back depending on where you shop and choose accordingly.

3. The Camelizer

The Camelizer is the brainchild of CamelCamelCamel, an Amazon price-tracking website. CamelCamelCamel tracks the price history of items sold on Amazon so shoppers can get a sense of any given product’s regular price — and thus can judge when a sale is really better than the ordinary selling price. The Camelizer extension provides users with price history charts without having to leave a product page on Amazon. So while you’re scoping out that Beats Bluetooth speaker, you can quickly glance at price changes over time before you check out. » MORE: Is Amazon Prime worth it? » MORE:

4. Keepa

Keepa says it tracks prices for more than five billion Amazon products. Using this browser extension will get you access to price history charts, price drops, availability alerts and daily deals on your favorite Amazon products. The website states that their price data is updated, at minimum, several times per day. For popular items being tracked by users, Keepa updates prices once every hour.

5. CouponCabin Sidekick

Similar to other shopping extensions mentioned, CouponCabin’s Sidekick browser add-on combines coupon codes with opportunities to earn cash back on purchases. And it works at more than 6,000 retailers, according to the company’s site. Like Rakuten’s browser extension, Sidekick shows cash back and coupon offers in the Google search results too.

6. Capital One Shopping

Capital One got in on the cash back and coupon game too, and you don’t have to bank with the company to use its deals site and browser extension, called Capital One Shopping. You know the drill by now. Add the extension to your browser and create a free account. Then voila, the coupon codes come to you as you shop, and there are chances for cash back at many retailers.

7. SimplyCodes

AI and crowdsourcing work together in SimplyCodes, which uses the power of collective shopping and algorithms to create a promo code platform. The platform hosts codes tested by actual people. SimplyCodes also provides automatic coupons and shopping rewards at more than 400,000 retailers. Check out the websites for these online shopping extensions for more information and for links to download them in your compatible browser of choice.

8. Coupert

Coupert is an AI shopping assistant that connects users with coupons, vouchers and special offers at 200,000 online stores. The browser extension searches coupons, price checks and tracks cash back.

9. RetailMeNot

RetailMeNot automatically finds and verifies coupon codes as you shop at more than 20,000 eligible stores. It also allows you to stack deals by applying cash back offers alongside discount codes. Check the websites for more information, and to download them in your browser of choice.
