Which Money-Saving Chrome Extension Actually Saves You The Most?

We tested 12 extensions to make sure you don't miss out on any discounts.
Last updated November 5, 2019

We’ve read a lot of reviews of “money-saving” browser extensions. Every extension promises to save you money, but no review could tell us exactly how much money we would save or which extension would save us the most.

We’ve reviewed and ranked 12 money-saving extensions for Google Chrome to find out which extension saves the most money. We tested all 12 extensions on real shopping baskets at 20 real online stores totalling $4,716.94 of purchases and we've calculated the savings.

We build and operate Wethrift, one of the extensons listed in this review. We help people save money when they shop online, and we want to make sure shoppers are using the best tools to save. We were also keen to see how our own extension stacked up against the competition.

The top 3 extensions worth installing.

No single browser extension is going to give you the best discount at every online store. Yet, you can combine top-notch browser extensions to give yourself the best chance of finding the highest-saving coupons and top cashback rates.

Wethrift had the best overall performance out of the extensions we tested. It saved us money at 16 out of the 20 stores we tested, including three stores that no other extensions had coupons for, and saved us the most off our total combined shopping trip. Wethrft also had coupons for three stores that no other extensions had any codes for, working well with even new, small and obscure online stores.

To find the best cashback opportunities and coupon codes for the largest online retailers we recommend installing either Coupert or Honey. Both of these extensions found working coupons at more than half of the stores we tested and saved us over 7% on our total checkout value.

Automatic Coupons had the smallest number of total users out of the extensions that we tried with fewer than 800 installs in the Chrome Web Store at the time of testing. Despite the low number of users and relatively poor user reviews, we decided to give it a shot.

It let us down.

Despite its name, we never could get Automatic Coupons’ auto-apply feature to work at any of the checkouts we tested, so we had to test each coupon manually.

Automatic Coupons saved us money at just four out of the 20 stores that we tested and offered inactive codes at another two stores. The extension appears to have been launched in the Chrome Web Store around June 2018, but it’s failed to gain much traction.

You can download Automatic Coupons from the Chrome Web Store, but we wouldn’t recommend it.

Pros
  • None
Cons
  • Very few active coupons at our tested stores
  • Auto-apply feature did not work
  • Mostly negative reviews

AVG Safe Price and Avast SafePrice are two of the most widely used money-saving Chrome extensions available, with almost 20 million combined installs. We’ve reviewed these two extensions together because the only difference we could find between them is the first half of their name. Everything else is identical. The design, the coupons, everything.

It appears that SafePrice is automatically installed when users install one of AVG or Avast’s free security products. Some user reviews appear to be a little confused about exactly what they are reviewing - a money saving extension or virus scanning software.

With such a large number of users and a majority of positive reviews, we were optimistic about saving some money with SafePrice. SafePrice appears to be saving some shoppers money but not us. SafePrice ranked dead last out of the extensions we tried, saving us money at just one of our tested stores.

Pros
  • It might already be installed in your browser
Cons
  • It might already be installed in your browser
  • Very few active coupons at our tested stores

BeFrugal appears to be all about cashback. Out of the extensions we tried, BeFrugal was one of the most frequent extensions to offer us cash back at the stores we tested.

While BeFrugal has generally positive reviews, some reviewers complain that BeFrugal promises to deliver higher cashback rates than other extensions, they were often left waiting to receive their cash.

"While Be Frugal does often offer higher cash-back rates than other sites, the issue I have with it is that it often will not credit me back any cash on shopping trips where I knew I bought something, This has happened often enough now that I almost exclusively use another site that's currently hitting at 100% for me whenever I shop at one of its retailers."
Review of BeFrugal by MJ Shute on the Google Play Store:

One unique feature of BeFrugal is that it will add it’s cute pig icon next to Google search results for stores where it can offer you cashback. Unfortunately, the cuteness of BeFrugal’s icon couldn’t make up for the fact that it failed to save us money at most of the stores we tested, ranking 2nd to last out of the extensions we tried.

BeFrugal has an auto-apply feature, but it only worked at one out of the four stores that it had any coupons for.

Pros
  • Auto-apply worked at some of the stoes we tested
  • Has lots of cash-back offers.
Cons
  • Only had active coupons at 3/20 stores we tested
  • Didn't find the best deal at 2/3 stores

Cently is simple. It does one thing well, and that thing is automatically testing coupons for you. It never offered us cashback, and it wouldn’t let us test coupon codes ourself. Cently’s auto-apply functionality is it’s best (and really it’s only) feature.

Cently does little more than pop up in the corner of your browser with a “Save Money” button. And if you click it you might save some money, but probably not as much as some of the other extensions we tried.

While Cently found the best deal at four out of the five stores that it had working coupon codes for, it only saved us money at a quarter of the stores that we tested. This was well short of the top performing extensions.

Pros
  • Simplest extension we tested
  • Auto-applying of coupons works well
  • Found the best deal at 4/5 stores
Cons
  • Only found active coupons at 5/20 stores

Coupert saved us money at 11 out of the 20 stores we tested (equaled by Honey) and managed to find the best deal at almost all of them. It saved us just a little less than Honey did, landing it in the third position in our ranking.

Coupert was an impressive contender, especially considering it only has a little over 83,000 users reported in the Chrome Web Store at the time of writing, compared to tens of millions of users of the largest players.

Coupert offered us cashback at some stores, but it was a little lower than the cashback offered by other extensions.

Coupert attempted to auto-apply codes at most stores, but on one occasion we caught Coupert failing to successfully apply a code that we knew was working. If we hadn't also tested the code manually, we would have missed the savings.

Pros
  • Found us the best discount almost all the time
Cons
  • Missed some working coupons when auto-applying

Guru was among the smaller extensions we reviewed with just over 18,000 installs reported in the Google Play Store at the time of writing and mostly positive user reviews.

Guru doesn’t auto-apply coupon codes, so you need to test them yourself. The extra copy and pasting would be fine if Guru saved us extra money. But in our test Guru saved us less than half as much as other extensions did, and only found the best deal at one out of the five stores that it successfully saved us money at.

Pros
  • Great design and easy to use
Cons
  • Only found the best deal at 2/5 stores

Honey is the undisputed giant of money-saving browser extensions. It boasts over 10 million installs in the Google Play store and over 140,000 user reviews (the next most reviewed extension we saw was Cently with just 11,300 reviews).

Honey’s strength comes from saving shoppers money at the most popular online stores. If you are looking to save money at smaller and more obscure stores, you might still have better luck Googling for a coupon or using our top ranked money saving extension.

Honey had the best auto-apply functionality out of the extensions we tested, but it didn’t always test as many codes as some of the competition.

Pros
  • Has plenty of cashback offers
Cons
  • Doesn't seem to test as many coupons as some of the other extensions
  • Has fewer coupons for for smaller and newer stores

RetailMeNot has been the king of coupon sites for over 13 years, dominating Google search results for “coupon code” searches. But it appears that RetailMeNot’s Genie extension hasn’t had the same level of success. Genie’s 376,000 installs reported in the Chrome Web Store are dwarfed by Honey’s 10 million, and Genie saved us money at just seven of the 20 stores we tested.

Genie appears to work best with larger online retailers. It found us the best deal at six out of the seven stores where it had a working coupon code and offered us some of the top cashback rates.

"You know... I love this extension when it actually saves me money. If it's a restaurant or Amazon, I typically don't get any working coupon codes... but it works at like, Bath & Body works, so that's always good!"
Review of Genie by Jordyn Andrews on the Google Play Store:

But Genie’s auto-apply feature didn’t always work, and it scored us a discount at less than half the stores we tested. If cashback is your thing, Genie might be worth installing, but if you’re looking to save money instantly with coupons, there are better options.

Pros
  • Offered some of the highest cash back rates
Cons
  • Found active coupons for less than half of our tested stores

Shopper.com came in 6th in our testing, saving us money at seven out of the 20 stores we tested.

We had a few issues using Shopper. The auto-apply feature didn’t work for many of the stores we tested, and we once spotted Shopper blindly testing coupon codes in a checkout’s credit card form instead of the coupon code box.

We also noticed that Shopper’s coupon codes aren’t labelled very clearly. You will often see coupons labelled with a confusing “OFF on selected products.”

Shopper didn’t have any unique discounts that couldn’t be found by using our top three extensions, so we’d recommend opting for one of our higher rated extensions.

Pros
  • For stores that had coupons, Shopper generally had more than most extensions.
Cons
  • Auto-apply didn't always work.
  • Had active coupons for less than half of our tested stores.

Smarty saved us money at just three out of the 20 stores that we tested and found the best deal at just one of those stores. Based on our tests, Smarty’s coupons appear to cater to only the largest online stores.

"I have not been on one website that gives me any reductions in cost!! Smarty always says that this site does not offer a reduction. So far, pretty disappointing!!"
Review of Smarty by Vicki Tanner on the Google Play Store:

Smarty did offer us some cashback at a few stores but not enough to earn our recommendation.

Pros
  • Auto-apply worked on most checkouts
Cons
  • Doesn't appear to have many stores
  • Savings aren't as good as other extensions

Wethrift was the simplest extension that we tried. It lets you know when it has found coupon codes for a store you are shopping at and you have to do the rest - choosing which codes to test and doing the copy and paste work yourself.

Wethrift’s strength is in its collection of coupons. It seems to have more coupons for more stores than the other extensions we tested. It was the only extension to save us money at three of the stores we tested, saved us money at an impressive total of 16 out of 20 stores, and found the best deal at 13 of those.

"Seriously, Honey gets all the fame but honestly I've found WeThrift to be MUCH more helpful, giving me codes for obscure websites. If I could give it six stars I would."
Review of Wethrift by Evan C on the Google Play Store:

Wethrift doesn’t offer cashback, but if you ever do any online shopping at smaller, boutique or more obscure online stores, you’ll want to have Wethrift installed.

Pros
  • Has coupons for stores that no other extension had
  • Saved us the most money overall
  • Usually found the best deal
Cons
  • Doesn't auto-apply coupons
  • Doesn't offer cash-back

Wikibuy ranked 4th overall in our roundup, saving us money at the same number of stores as RetailMeNot’s Genie extension and Shopper.com.

Wikibuy’s auto-apply feature worked at most checkouts and found us the best deal at five out of seven stores. Wikibuy saved us a lot of money compared to most of the extensions we tried but didn’t find any savings that weren’t discovered by our top three extensions.

Pros
  • Auto-apply works great
  • Also offers cash-back
Cons
  • Saved us money at less than half the stores we tested

Four "money-saving" extensions to avoid

Our testing started with 17 extensions, but we ended up only including 12 in the final review after we realised that 4 of the extensions in our original line up were either no longer working or never worked at all. Another extension Avast SafePrice turned out to be an exact clone of AVG SafePrice. Here are the 4 “money-saving” Chrome extensions that aren’t worth your time.

All Online Promo Codes has less than 400 installs and 9 reviews reported in the Chrome Web Store, and we had a feeling it wouldn’t do much based on the Web Store screenshots. We were right. This extension does little more than link to the All Online Promo Codes website, which also isn’t worth your time.

BonusApp looked a little more trustworthy with almost 24,000 users. The app claims that it “automatically finds and applies the best coupon at your checkout.” In our experience the BonusApp extension does little more than display a list of product deals from Indian online stores.

CouponMate has around 4,000 users and claims to offer similar auto-apply functionality of other money-saving extensions. Although CouponMate had coupons for some of the stores we tested, every single code was labelled as “added 2 years ago.” Our hopes that you can save any money with this extension aren’t very high.

Coupons Vault has 4,000 installs and almost 100 reviews. The Chrome Web Store page for Coupons Vault includes a video that shows similar functionality to other extensions. In reality, Coupons Vault does little more than display an ad for Coupons.com in the corner of your browser.

Methodology: How we tested the top money-saving Chrome extensions

What this test covers

The aim of this test was to find the money-saving extensions for Google Chrome that save us the most money off of the total checkout value from a fictional shopping trip to 20 online stores after applying any available coupon or discount codes found by the extension.

What this test does not cover

Many money-saving extensions offer varying rates of cashback when shopping at different stores. Cashback offers require making a purchase and often waiting up to several months to receive any actual cash back.

Determining the actual savings made through cashback offers promoted by money-saving extensions is difficult. While we have made note of cashback offers in our reviews of each extension, we haven’t included cashback as a component of our scoring or ranking of the extensions tested.

How we selected stores to test

We aimed to develop a list of 20 stores that represented a cross-section of those where shoppers could potentially save money using any of the extensions we tried. We aimed to include small, mid-sized, and large online retailers across a range of categories.

To prepare this list, we used some advanced Google search queries to find a list of stores that each extension publicly advertises coupons for. For example, we can find around 4,000 stores that Honey has coupons for by searching Googgle for “site:joinhoney.com.”

We selected stores at random from this list, and only included stores in our final list where at least one of the extensions delivered a discount.

How we prepared our shopping cart at each store

Some coupon codes only work on particular products or categories. To best account for this, we aimed to create a shopping basket at each store with non-sale items from all of that store’s major product categories. Each extension was tested using the same shopping cart at each store.
