9 Browser Extensions for Easily Finding Coupons

Rather than search for promo codes yourself, download a browser extension for shopping and let it find the deals for you, in seconds.

If you’re a savvy deal seeker looking to save money, browser extensions can help.

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 nine 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.

Nerdy Perspective

"I add items to my Honey droplist when I don't want to track prices manually. If the item hits the price threshold I've set, I'll get an email alerting me to the drop. Most recently, I added a wooden toy barn to my droplist. I've had my eye on it for a long time, but $54 was just too pricey. But Honey emailed me alerting me to a price drop — now it was only $34. I bought it right away and put it away for Christmas. A total win in my book."

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. Keepa

Keepa says it tracks prices for more than 6 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.

4. Capital One Shopping

You don’t have to bank with Capital One to use its deals site and browser extension, called Capital One Shopping. Add the extension to your browser and create a free account. Coupon codes come to you as you shop, and there are chances for cash back at many retailers.

5. 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.

Nerdy Perspective

"Amazon has price tracking built right into product pages now, but I still keep The Camelizer Chrome extension pinned. I find it faster to pull up and the tracking history easier to read through when I want to quickly confirm whether an advertised sale price is really a deal."

6. 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 2,000 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.

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 600,000 retailers.

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.

He’s recorded and written about his experience testing popular gig jobs like driving for Uber, delivering with DoorDash and full-service shopping for Instacart. He loves making an extra buck, but laments the hours of awkward silence he endured as an Uber driver (never again).

Cool kids might call him a content creator because he makes YouTube videos for the NerdWallet channel and app, but he himself is no longer very cool. Ask him about budgeting apps — he's tried most of them, but still prefers a good ole Google sheet to track spending. Then be sure to smash that “like” and “subscribe” button.

Before NerdWallet, Tommy held decidedly more boring jobs at Fannie Mae and Booz Allen Hamilton. Today, he feels super privileged to write for you, the consumer.
