There are many reasons we shop online, not the least of them being convenience and selection: with just a couple mouse clicks, we can get almost any item from anywhere in the world dropped off on our doorstep in a matter of days.

Still, the biggest motivating factor driving most of us to shop online is the desire to save money. We rightly recognize that most items are cheaper online than in brick-and-mortar stores — and that’s before taking into account things like rewards and cash-back shopping programs, which can dramatically increase our overall savings.

But how can you be sure that you really are getting the absolute best deal when you shop online?

That’s one of the questions we’ll touch on in this Wikibuy review, which highlights the features, benefits and drawbacks of this free service provided by Capital One.

What Is Wikibuy?

For most of us, Amazon is the go-to online shopping destination. It’s where we look first and, increasingly, it’s the only place we look at all. Amazon has such a strong reputation for offering low prices that we’ve come to take that as a given.

But it’s not always the case that Amazon actually has the best deal on a particular item. There are tens of thousands of online retailers of all shapes and sizes, and that’s to say nothing of the thousands of private sellers operating on sites like eBay.

Meanwhile, coupon and promo codes can be a great way to save money, but they’re often frustrating; finding legit codes is hard, and you can waste a lot of time sifting through mounds of web spam before finding one that actually works.

Wikibuy is a free browser extension that aims to solve both of those online shopping problems. It will show you where to find the best price and then provide working coupon or promo codes so that you can save even more.

Wikibuy has a few distinct functions and features, which we’ll list and explain in the next section. But at the most basic level, it acts as an online shopping price comparison tool. Once installed, it will tell you whether or not the Amazon item you’re browsing is available somewhere else for less money.

Similarly to the more well-known browser extension called Honey, Wikibuy also searches the web for coupon and promo codes, and then automatically tests them for validity. When it finds one that works, it applies the code to your cart at checkout.

Wikibuy’s Five Money-Saving Features

Wikibuy offers more than one way to help save money. The five features listed below each provide online shoppers with a unique and valuable benefit.

#1. Amazon Price Comparison Tool

If your primary online shopping destination is Amazon, you’re going to love Wikibuy’s Amazon price comparison tool. When you’re browsing on Amazon, Wikibuy works in the background checking prices at hundreds of other retailers and sellers. The plugin adds a widget directly to the Amazon page that tells you whether you’ve found the best deal, as was the case for the Adidas t-shirt in the screenshot below.

We added the red box to highlight the Wikibuy widget.

But as we noted above, Amazon doesn’t always have the best price. For example, when I was researching for this article I discovered that I could save $7 on Apple AirPods by purchasing them off Amazon. These savings opportunities are also shown directly on the Amazon page via the Wikibuy widget.

Clicking on the Wikibuy icon opens a popup with a few more details and a comparison table:

Clicking “W. Save $7” opens the product comparison table shown above.

Clicking “Continue to Wikibuy” takes you to a page where you can view not only the top offers for the item in Wikibuy’s database, but also historical price data. In the screenshot below, you can see that the lower price on AirPods is offered by B&H Photo Video. Just click “Save $7” and you’re sent to B&H’s website, where you can complete the transaction.

Every product in the Wikibuy database has a product page like the one shown above.

#2. Automated Coupon Codes

When you’re shopping on a participating retailer’s website, Wikibuy will test out various coupon codes. There are hundreds of participating sites, including AT&T, Dell, Kohl’s, T.J.Maxx, Walmart and more.

Where do the codes come from? Well, the answer to that question is part of what makes Wikibuy such a powerful money-saving tool.

While some of the codes Wikibuy tests are publicly available, others are crowdsourced: they’re codes that have previously been used by other Wikibuy members.

Here’s an example of the system in action.

Say your favorite clothing brand emails you a special “members only” promotional code for 25% off your next order. When you enter that code at checkout, Wikibuy adds it to its database of codes for that site. The next time a Wikibuy user goes to check out with that merchant, the browser extension will test the code to see if it’s still valid.

This means you can potentially tap into a wide array of savings that you would never have known existed or had access to.

Wikibuy tests all of the codes in its database and applies the best of the bunch. Depending on the store’s policy, you may be able to use more than one code — as was the case in the screenshot below.

In the transaction above, waiting about two seconds saved over $16.

Whether you’re able to use one code, multiple codes or none, the entire process is handled automatically and usually takes just a couple of seconds.

#3. Universal Product Search Engine

Wikibuy’s product search engine is essentially the same feature as the Amazon price comparison widget, except that you don’t need to be on Amazon to use it — you can simply open the browser extension and enter the item you’re shopping for:

Wikibuy Product Search Engine

Clicking on the product’s name will take you to a Wikibuy search results page, where you can browse a variety of matching offers.

Wikibuy product search results

The product search engine results page has all sorts of useful information including:

  • Offers from other sellers including tax and shipping charges.
  • A chart showing the price history of the item from the past 30 up to the past 365 days.
  • 30-day insights, including current savings; Amazon’s price; the average, best and highest price; and price volatility as a percentage.
  • The top alternatives (similar products to the one you’re watching).
  • YouTube reviews.
  • Professional reviews.
  • Related products.

You can also use the search engine when browsing products in brick-and-mortar stores. Just scan the barcode and you’ll be taken directly to the product’s Wikibuy page.

#4. Wikibuy Credits

Wikibuy Credits are a percentage of cash-back available when you shop with partnered retailers. When you’re on the site of a partner, the Wikibuy extension button will show the percentage of cash-back you can earn. All you have to do is “activate” the offer by clicking the button — it’s essentially free money.

Additionally, there may be local stores in your area that have partnered with Wikibuy to offer credits. To earn, enroll in the Wikibuy Local Offers program. Link an eligible debit or credit card, and then check the “Local Offers” section on the site or app to see the deals near you. You’ll earn Wikibuy Credits when you use the linked card to take advantage of these offers.

This method of earning cash-back is similar to that offered by Drop and Dosh, two other free apps. 

Wikibuy Credits — as with Drop and Dosh points — can be used to purchase gift cards from dozens of companies, including Barnes & Noble, Sephora, Staples, Walmart and others.

#5. Price Drop Notifications

As its name suggests, Wikibuy’s price drop notification feature lets you know when an item goes down in price. When paired with the service’s historical price charts (which allow you to view an item’s price data over a period of 30 days to one year) this has the potential to be a valuable tool that helps you avoid overpaying.

However, after singing up for and testing the service, we were uncertain about how the price drop feature actually works. The tool is poorly documented in Wikibuy’s help files, and our confusion stemmed in part from trying to understand the following settings panel in the user dashboard: 

Wikibuy Price Drop Settings 
As you can see, the settings allow you to choose when and where you’d like to be “notified.” But as you may have also noticed, the options don’t really make sense in the context of price drop notifications. 

So we reached out to Wikibuy for clarification, and here’s the answer: the settings above refer to on page notifications. They control when and where you’re alerted about a lower price for an item you’re actively shopping for and/or in the process of buying, and are totally unrelated to price drops. 

Given that, we still wanted to understand and clarify how the price drop feature works. So here are some key facts, based on our conversations with the company.

  • Users are notified of price drops by email only — there are no text messages or push notifications.
  • You cannot choose which items you’d like to be notified about. The extension keeps a record of all the items you’ve viewed, and it may (or may not) alert you about any number of them. 
  • You cannot set a notification threshold — the service decides when a price decrease is worth flagging.
  • Emails are sent twice per week — typically on Tuesday and Thursday. However, you’ll usually only receive an email on one of those days.
  • Not all users receive price drop notifications. According to Wikibuy, only people who have viewed more than four products and have $20 in cumulative savings will receive an email.

The lack of customization options limits the feature’s usefulness: since you can’t control what you’ll be notified about (or when), it doesn’t make sense to defer a purchase until there’s a great price on a given item — because you might never be notified about that deal.

With that said, it can still be helpful to receive price notifications about things like big-ticket items that you don’t need to purchase immediately (where a 10% discount might result in hundreds of dollars of savings), and seasonal items (like sporting goods) that you’re willing to buy in the off season. 

How to Install Wikibuy

The Wikibuy extension is quick and easy to install.

  • Step #1: Go to Wikibuy.com, enter your email address and create a password. You can also log in with your Gmail or Facebook account.
  • Step #2: Select “Add Wikibuy to X” (where “X” represents the web browser you use). If you don’t see “Add Wikibuy,” update your browser or switch to a compatible one. Wikibuy is compatible with the latest versions of Google Chrome, Mozilla Firefox, Microsoft Edge and Safari.
  • Step #3: Select “Add Extension” or “Allow” when prompted. If you’re redirected to the add-on or extension store for your browser, select “Get” or “Install” on the store page.
  • Step #4: Enter your zip code (for the local offers page), indicate if you have Amazon Prime (so Wikibuy can accurately calculate shipping costs), accept the Wikibuy Terms of Service and Privacy Policy, and choose “Continue.”
  • Step #5: Select “Continue to my Wikibuy page” or close out the window.

Once Wikibuy is installed, you’ll see the green Wikibuy “W” followed by a period (W.) in the extension section of your web browser.

Wikibuy iOS and Android App

The Wikibuy app can be downloaded from the App Store for your iPhone or the Google Play Store for your Android device.

The app is not the same as the browser extension, and you should view it more as a companion product. It allows you to search for items or scan barcodes when you’re out shopping, and it will show you the best prices from popular retailers. You then have the option to order the item at the lower price directly through the app.

Wikibuy Downsides

  • It can slow down your browser. Wikibuy, like any other extension or add-on software, has the potential to slow down your browser.
  • It collects a ton of data. Wikibuy tracks and records things like user-provided information (email, address, etc.), cookies, location information, third-party beacons and buttons, payment information and transaction data. While Wikibuy is a legit service owned by Capital One, it’s important to always remember the adage that in the internet age, if a service is free then you are the product. For many users, providing that data is a fair exchange for the savings you can get by using the service.
  • It may not always find the best price. There are millions of retailers on the web and Wikibuy (or any similar site) can’t possibly monitor them all. Wikibuy focuses on the largest, most popular stores. That does eliminate a lot of the research a buyer has to do, but not all of it. Would I bother manually researching the lowest price on a 12-pack of paper towels? No. But if I were making a substantial purchase — like a mattress or a computer — I would use Wikibuy as a starting point and do a little additional research myself.
  • Offers are sometimes out of date, which wastes time. Because retailers change their prices so frequently, including coupon codes, Wikibuy may show you an offer that’s no longer available when you try to place the order. Similarly, sometimes Wikibuy will show you an item that’s already been sold on eBay, or that’s recently become out of stock.
  • You may be able to get a better deal by utilizing a cash-back portal. It can pay to think about more than the sticker price. For example, if Wikibuy shows you an offer that’s 5% less than Amazon’s price, but you can get 10% cash-back by shopping through a rewards portal like Swagbucks or Rakuten, then you’re better off opting for the latter in spite of the higher price.

Wikibuy vs. Honey

If the whole concept of Wikibuy seems familiar, you may have heard of Honey, which is another browser extension that automatically applies coupon codes for the items in your shopping cart on big retail websites.

Honey (which is now owned by PayPal) is particularly useful for Amazon shoppers. It will show you if an item is available from a different seller (i.e., a third-party seller) on the site for a lower price, and shows you the Amazon price history of the item so you can see if now is the best time to buy or if the price tends to fluctuate.

But Honey doesn’t monitor other sites for the lowest price, nor is there a mobile app (meaning you can only use the site on a desktop).

Frequently Asked Questions

Wikibuy is currently only available in the United States, but plans to expand internationally in the future.

Wikibuy Review — Final Thoughts

Once I find something I want to buy online, it becomes a game for me to find the lowest price. Whether that’s using a site like Cashback Monitor to know where I can get the highest cash-back, setting deal alerts to aid in saving money, or utilizing a credit card strategy like the Chase Trifecta that’s going to maximize my rewards.

I enjoy this game. It takes time, but saving a few extra bucks puts a smile on my face.

Others (like my wife) don’t enjoy this game at all. They want the simplest and most straightforward method for finding a great deal. For those looking for a shortcut to finding the best deal online, WikiBuy is certainly a great, simple and easy-to-use option.
