12 Best Browser Extensions to Save Money While Shopping Online



Americans are shopping online more than ever before. According to the United States Census Bureau, online retailers in the U.S. took in about $759 billion in 2020. That’s more than 13% of all retail sales in the country.

As we spend more online, we’ve become more interested in finding ways to save online. We use sites to compare prices across multiple sites and search for coupon codes that provide deals like discounts or free shipping. Tricks like that can save you money, but they take extra time — sometimes more than it’s worth to save a dollar or two.

Fortunately, there’s an easier way to save when you shop online. All you have to do is install a browser extension, a plug-in that extends the capabilities of a Web browser such as Chrome, Firefox, or Safari. But to leverage the online savings, you need to choose the best browser extension for your shopping needs. 

Best Browser Extensions to Save Money While Shopping Online

Several money-saving browser extensions can do the work of online bargain-hunting for you. Some compare prices, some find and apply coupon codes, and some help you cash in on cash-back deals. And the best of the bunch can do all three.

1. Capital One Shopping

The Capital One Shopping add-on is an online shopping assistant that uses real-time data from its millions of users to find you better deals. As more people use Capital One Shopping, it gets better at finding low prices and coupon codes that work.

Capital One Shopping combines several of the features of other browser add-ons in one. These include:

  • Price Checking. When you search for a product online or scan a bar code in a store, Capital One Shopping searches for better prices elsewhere. It displays all the prices it finds from Amazon sellers and other top retailers on a single page. 
  • Coupon Checking. When you add something to your online shopping cart, Capital One Shopping goes into coupon-checking mode. It checks multiple coupon codes to see which ones have worked for other Capital One Shopping users and automatically applies the one that gives you the bigger discount. 
  • Price Tracking. If you decide not to make a purchase, Capital One Shopping continues to track prices for the product. If it goes on sale, the app notifies you so you can jump on the bargain.
  • Shopping Rewards. Capital One Shopping also functions as a rewards app. When you shop through the extension, you earn rewards credits at its partner stores, including eBay and Walmart. You can cash in your credits for gift cards at these same stores at Capital One Shopping’s website.

Capital One Shopping is available for Chrome, Firefox, Microsoft Edge, and Safari. There’s also a Capital One Shopping mobile app for iOS and Android.

2. Honey

Of all the money-saving extensions you can add to your browser, none get more rave reviews than Honey by PayPal. This free add-on saves you money in various ways:

  • Coupon Codes. Honey automatically seeks out promo codes for over 30,000 online retailers, including Amazon, Macy’s, Target, and even eateries such as Pizza Hut. The extension compares all the available codes for the site you’re shopping and automatically applies the one that gives you the biggest discount.
  • Amazon Price Comparison. When you shop on Amazon, Honey tells you which of the site’s many sellers offers the best final price on a product, including sales tax and shipping. If you’re an Amazon Prime member, Honey factors that in when calculating shipping costs.
  • Price History. Honey also tracks price changes on Amazon. It can show you how a product’s price has changed over the last 30, 60, 90, or 120 days. If you don’t like the current price, you can add the product to your Droplist and have Honey notify you when the price drops.
  • Cash Back. Shopping with Honey earns you cash back, or Honey Gold, at over 4,500 participating sites, including Macy’s, Groupon, and Walmart. Just click a browser button to activate your rewards, and Honey applies them while searching for coupons at checkout. You can cash in Honey Gold for gift cards from participating stores.
  • Referral Bonuses. You can also earn bonuses for referring your friends to Honey. You send them a link, and when they sign up and make their first purchase, you earn 500 Honey Gold — the equivalent of $5.

Honey works with Chrome, Edge, Firefox, Opera, and Safari browsers.

Honey also offers a rewards app for iOS versions 13 and up called the Honey Smart Shopping Assistant. Like the browser add-on, it can automatically find and apply coupon codes and deals, but it has an extra perk: You can access all your favorite stores at once through the app. That allows you to find the best deal and cash in without having to visit multiple sites.

3. Mulberry

Should you buy an extended warranty or product protection plan on the laptop, mattress, or major kitchen appliance you’re planning to buy online soon? You’d probably answer “yes” were it not for the added cost of the warranty and the distinct possibility you’ll never need to invoke it.

Mulberry takes care of the cost question, at least. It’s a free browser extension that makes it easy to pick up free product protection plans on items purchased through 5,000+ online retailers including Amazon, Wayfair, Best Buy, and more. No more wondering whether a paid product protection plan is worth paying for when you’re not sure you’ll ever use it — because you don’t have to pay for it.

Mulberry’s free plan provides 12 months of free protection with no confusing contracts or hidden fees. Mulberry’s paid plans provide protection for longer time spans. That’s great for durable items that you hope to keep around for a while. And no matter which plan you choose, the claims process is a breeze thanks to automated approvals and 24/7 support.


4. Rakuten Cash Back Button

The rewards site Rakuten (formerly known as Ebates) offers a browser extension called the Cash Back Button. It gives you access to both cash back and coupon codes at over 2,500 stores. 

The extension displays a pop-up message to tell you when there’s cash back available at a store you’re shopping. If there is, you can just click to activate it. Rakuten can even show you which sites have cash-back offers directly in your search results on Google, Yahoo, or Bing. You can compare cash-back offers across multiple stores and choose the best deal. 

The money you earn goes into your Rakuten account, and you can cash it in once per quarter for a check or PayPal credit. You can also choose to use the Cash Back for Change feature to donate some of your credit to charity. Rakuten rounds your check or credit down to the nearest dollar and divides the change among three worthy charities.

The Cash Back Button also seeks out coupon codes when you shop. Just click “Apply Coupon” at checkout, and the extension automatically applies the coupon or promo code that gives you the best discount. It can even let you know when there’s a Groupon offer available at a local business you search for on Yelp or Google Maps.

The Rakuten Cash Back Button is free to install. It’s available for Google Chrome, Safari, Firefox, and Microsoft Edge.

5. CouponCabin Sidekick

CouponCabin Sidekick is a free browser extension from the rewards site CouponCabin. It has two primary features: coupon codes and cash-back offers.

To get cash back from CouponCabin Sidekick, you must log in to your CouponCabin account before shopping (you can’t receive cash back if you added a product to your cart before logging in). Click through from your account to one of CouponCabin’s 3,500 partner stores to see how much cash back you can earn there. 

There are a few limitations when shopping with Sidekick. You can’t earn cash back on orders through a store’s mobile app or those placed online and picked up in-store. You can’t use the extension with a firewall or ad-blocking software. And you can’t combine cash-back offers from Sidekick with any coupon that’s not from CouponCabin, even one from the store itself.

On the plus side, CouponCabin Sidekick lists the available offers both when you shop and when you search on Google. For instance, let’s say you’re searching for a DVD set. Right in your search results above the name of each store that offers the DVD set, the extension displays a little cabin icon showing what discounts and cash-back offers are available at that particular store.

CouponCabin Sidekick is available for Chrome, Edge, Firefox, and Safari.


6. Ibotta

Ibotta, a popular mobile coupon app, is also now available as a Firefox or Chrome extension. To use the Ibotta extension, you must first set up an Ibotta account if you don’t already have one. The Ibotta extension requires you to log in to your account before shopping to earn rewards. 

It works with over 1,000 online retailers, including Overstock, Petco, and Bed Bath & Beyond. When you purchase through one of these sites, the app displays a button showing how much cash back you can earn. Click it to activate rewards, then shop and pay as usual.

This browser add-on also works with online grocery delivery services like Instacart. When you shop through these services, the extension highlights cash-back offers with a pink box around the cash-back-eligible product. Click to buy, and the cash shows up in your Ibotta account within 24 hours. 

As soon as you have at least $20 in your account, you can log into the Ibotta app on your mobile device to cash in your earnings. You can opt for a bank transfer, PayPal deposit, or gift card.

Reach out Ibotta review for more information.


7. Earny

If you like lotteries and sweepstakes, Earny is for you. This Chrome extension earns you cash back on your online purchases and enters you into a prize drawing with every action you take on the app. The more tickets you earn, the higher your chances of winning prizes such as cash, prepaid Visa cards, and free Amazon gift cards.

Other features of Earny include:

  • Cash back on up to 5,000 brands
  • Extra cash back when you share links with friends
  • Price tracking and price drop alerts for goods on your Amazon wish lists
  • Up to 90 days of price protection on purchases at more than 15 major retailers
  • Notifications when an Amazon package arrives late so you can request compensation

8. The Camelizer

Frequent Amazon shoppers already know about the website CamelCamelCamel, which tracks the prices of millions of Amazon products over time. Since prices on Amazon change daily (sometimes even minute by minute), being able to see a product’s price history helps you figure out whether the current price is a good deal or not. 

CamelCamelCamel also offers a free browser extension called The Camelizer for Chrome, Edge, Firefox, Opera, and Safari. This add-on lets you see a product’s price history directly from Amazon without having to visit a separate page. And like the website, it can also import your Amazon wish list and alert you when the price of any product on it drops.

Currently, The Camelizer only tracks Amazon prices. But it has covered a couple of other retailers in the past and could do so again in the future.


The free PriceBlink extension for Chrome, Firefox, and Safari helps you find the best price for a product. But instead of tracking prices over time on just one site like The Camelizer does, PriceBlink compares prices across thousands of sites and lets you know when there’s a better deal elsewhere.

For instance, let’s say you’re looking at a pair of boots Amazon sells for $100. PriceBlink recognizes the brand and style and instantly searches more than 4,000 other sites to see if any other retailer carries the same boots for less. If it finds one, the lower price pops up on the PriceBlink toolbar, and you can simply click to view the listing.

PriceBlink can also help you find coupon codes. When you visit a retail site, the PriceBlink toolbar shows you a list of the best coupons available on that site. Click on an offer to copy the coupon code to your clipboard. Then, paste it into the appropriate field at checkout. 

If you’re not sure what product you want to buy, PriceBlink can help you there too. When looking at a product on a retail site, you can click “Ratings” in the PriceBlink toolbar to see how users rated the product on other sites. That gives you a better overall picture of users’ opinions than the ratings on just one site.

If that sounds like a lot of information to have cluttering up your screen, don’t worry. The PriceBlink toolbar stays hidden most of the time and only pops up when it finds you a deal on a particular product you’re viewing.


10. Fakespot

Comparing online product reviews through PriceBlink is handy, but there’s one problem: You can’t be sure those reviews are authentic. Sometimes, sellers on Amazon and other sites hire people to post good reviews for their products. You can’t always tell if a product has a 5-star overall rating because it’s a fantastic product or because the company paid lots of people to say it is.

That’s where Fakespot comes in. This free plug-in for Firefox or Chrome (also available as an iOS or Android app) analyzes reviews on Amazon, Walmart, Best Buy, TripAdvisor, Sephora, Steam, or Yelp. It looks for suspicious patterns that suggest the reviews are fake. It then gives the product a grade from A to F to indicate how trustworthy the reviews are. 

If you want, you can click on this grade to see a more detailed analysis showing which phrases reviewers are using most often and what percentage of the reviews appear to be legit. It also highlights the most important points made in the legitimate reviews. 

Fakespot also checks ratings for eBay and third-party sellers on Amazon. If the reviews suggest a seller is unreliable, the extension recommends an alternative seller for the same product. 

Fakespot has several options to make it easier to use. For example, it can show Fakespot grades on Amazon product pages and listing pages so you can simply skip over products with a bunch of bogus reviews. It can also sort and filter Google search results based on Fakespot grades. But you can turn these features off if you don’t want to use them.

To use Fakespot, you must either have a Google account or create a Fakespot account. If you choose the latter option, Fakespot tracks your product searches and sends you product updates and offers from its partners.


11. InvisibleHand

InvisibleHand compares prices when you shop and links to the lowest price on a product you’re viewing. But InvisibleHand works with fewer retailers than PriceBlink: Sears, Lowe’s, Best Buy, and Newegg.

The primary use of InvisibleHand is for finding travel deals. When you search for flights on an airline’s website, InvisibleHand lets you know if there’s a cheaper flight available to the same destination and gives you a link directly to the lowest price. It can also find deals on hotels and rental cars.

Another unique feature of InvisibleHand is that it can find hidden prices on retail sites. Some retailers don’t reveal the price of merchandise until you put it in your shopping cart. Typically, they do that because they’re not allowed to advertise the product for less than a certain minimum price. InvisibleHand gets around that limitation, ferreting out and showing you the real price of the product.

InvisibleHand is available for Chrome, Firefox, and Edge.


12. Piggy

The Piggy extension for Chrome, Firefox, and Safari is primarily a coupon finder. It works with thousands of online stores, including major retailers like Macy’s and Walmart, hotel chains like Hilton, car rental services like Hertz, and deal sites like Groupon. When you shop on these sites, Piggy seeks out and tests every coupon code available for that site and applies the one that gives you the most savings.

However, Piggy has a perk other coupon apps don’t have: It can find you special deals at hotels, including rates hotels haven’t officially published online. That makes Piggy an excellent choice for frequent travelers.

Piggy also has a cash-back feature. In addition to looking for coupons when you check out, it lets you earn cash back at more than 6,000 stores. When the earnings in your Piggy account reach $25, it automatically sends you a check.


Final Word

Each of these browser extensions can save you money on its own. However, there’s no need to limit yourself to just one. 

For instance, if you’re shopping on Amazon, you can use Fakespot to see if the reviews are legit. If it looks good, you can consult The Camelizer to see how Amazon’s price for the product looks today and whether you should wait for a better deal. And finally, you can check PriceBlink to see if there’s a better price available on another site.

Even when two different add-ons have similar benefits — for instance, finding coupon codes and cash-back offers — it can’t hurt to have both installed. The list of retail sites that work with Honey isn’t necessarily identical to the list for Rakuten or CouponCabin Sidekick, so installing all three increases your chances of finding a deal. 

You can’t earn cash back from more than one extension for the same purchase. However, you can sometimes use a coupon code from one and earn cash back from another. By having an assortment of browser add-ons to choose from, you can ensure you always get the best possible combination of deals.
