Let‘s dive in and explore how these extensions can help you keep more money in your wallet!

Why Browser Extensions Should Be In Every Savvy Shopper‘s Toolkit

Browser extensions are software programs that add functionality to your internet browser. They seamlessly integrate with your shopping sites to help save in a few ways:

  • Find Coupons Automatically: Extensions scan for applicable coupon codes and apply them at checkout to save you time and effort. No more fruitless searching!

  • Compare Prices Across Retailers: Extensions check competitor retailers and show you the site with the best price. This allows you to instantly find the best deal.

  • Earn Cashback on Purchases: Cashback extensions give you a percentage of your purchase amount back as cash rewards. It‘s like getting paid to shop.

  • Alert Price Drops: Some extensions monitor products and notify you when the price drops, so you can snag the lowest price.

  • Enhanced User Experience: By integrating directly into your browser, extensions provide a seamless way to save each time you shop online.

According to a Pollfish survey, 68% of online shoppers use browser extensions specifically for coupons and price comparisons. And browser extension usage grows annually by over 14%.

It‘s clear that savvy shoppers have caught onto how these tools optimize online shopping. Now let‘s explore the top 12 extensions to supercharge your savings.

1. Honey – Best for Automatic Coupons & Rewards

With over 17 million members and a 4.8/5 star rating, Honey is one of the most popular and highest rated shopping extensions.

Honey‘s key strength is automatically applying coupons and earning you rewards. Whenever you checkout online, Honey scans its database of coupon codes and tests them to find savings for you. This removes the hassle of manually searching for discount codes.

I especially like that Honey works seamlessly across 30,000+ online stores including fashion, travel, electronics, and other top sites. And it perfectly integrates into the checkout process for sites like Amazon and Target.

The extension also provides Honey Gold rewards when you purchase with applied coupons. Over time, this gold can be exchanged for gift card rewards at major retailers like Amazon and eBay.

For set-it-and-forget-it coupon savings at the most frequented online stores, Honey is hands down the top browser extension.

2. Rakuten – Best Big Brand Cashback

Rakuten is arguably the largest and most reputable cashback shopping portal, with over 10 million members worldwide.

The Rakuten browser extension makes earning cashback seamless by automatically activating it when you visit and shop at over 3,500 partner stores. These include go-to brands like Nike, Macy‘s,, and many more top retailers.

Unlike some other cashback extensions, Rakuten pays directly without you needing promo codes or other hassles. Simply enable the extension, and then you‘ll receive your cashback percentage on qualifying purchases at Rakuten network sites.

Payments are made quarterly by check or PayPal, which is more delayed compared to instant options from other tools. But the sheer volume of big brand partnerships makes Rakuten the best extension for earning cashback on places you already frequent.

3. Capital One Shopping – Top for Price Comparisons

As a reputable financial institution, Capital One offers a solid shopping extension for price tracking and comparisons.

The Capital One Shopping browser extension automatically looks for coupon codes to apply at checkout for extra savings on top of what you already save.

But where it really shines is comparing prices across retailers to instantly identify the best deal. The tool checks competitors, factors in shipping costs, loyalty program discounts and more to showcase the overall lowest price. This makes it easy to find the smartest purchase option without manually cross-checking sites.

Capital One Shopping also features price drop alerts, cashback rewards on purchases and is offered as both an extension and mobile app. Helpful features from a name you can trust.

4. CouponCabin – Best for Exclusive Coupon Codes

True to its name, CouponCabin is all about stacking savings through coupon codes and cashback.

Beyond coupons, you can earn cashback on purchases made through CouponCabin. The cashback earnings are quickly redeemable via PayPal, which is faster compared to the quarterly payouts of some competitors.

Overall, if you want reliable access to the latest coupon codes – including hard-to-find exclusives – at all your favorite stores, CouponCabin is a top choice.

5. Wikibuy – Most Comprehensive Free Extension

Wikibuy is a impressively comprehensive free extension that combines both coupon finding and price tracking capabilities.

I also like that Wikibuy allows you to easily track prices on products across retailer sites. It monitors items for price drops and alerts you of lower prices so you can snag the best deals.

For a free extension, Wikibuy combines some of the best features into one – from broad coupon finding to proactive price monitoring.

6. InvisibleHand – Best for Proactive Deal Notifications

While some extensions wait for you to visit a retailer site to look for savings, InvisibleHand takes a more proactive approach.

This handy shopping tool automatically alerts you when cheaper prices are found for items in your cart or on your wishlists across merchant sites. So you don‘t have to go deal hunting – the deals come straight to you!

InvisibleHand also tests and applies coupon codes, tracks price histories, and provides cashback when shopping online. The tool works across over 300 top retailers include Walmart, BestBuy, Target, and more.

For shoppers who want real-time notifications sent to them when better deals are identified, InvisibleHand is the most proactive savings extension.

Finding the lowest available price on products typically requires crisscrossing from retailer to retailer to compare.

PriceBlink eliminates this hassle by showing you comparative pricing all in one place. After installing the PriceBlink browser extension, you can view cost comparison charts as you browse products online. This allows you to instantly spot the retailer offering the best deal.

Going beyond just cost comparisons, PriceBlink also automatically checks and tests promo codes to stack on additional savings for you at checkout.

11. eBay Coupon – Best Extension for eBay Shoppers

Diehard eBay shoppers need to grab the eBay Coupon extension for exclusive access to discounts on this popular marketplace.

You can benefit from sitewide discounts in addition to category or seller specific promo codes. eBay Coupon also automatically notifies you when new eBay coupon offers become available.
