Lots of people shop online. It’s hard to beat the convenience of buying things from your couch and waiting for them to arrive at your door. Often, you can even find deals online that aren’t available in stores.

One great way to save money while shopping online is to comparison shop, but it takes time and effort to compare prices from different online stores. Wikibuy is an app that does the comparison shopping for you, making sure that you always get the best deal possible.

What is Wikibuy?

Wikibuy is an app offered by Capital One, the bank and credit card issuer. You can add the app to your web browser and use it to help you compare deals on all the things that you buy online. Once you’ve added the app to your browser, you’re ready to start shopping. The app automatically informs you if there’s a better deal available on a different site.

Wikibuy also helps you save money in other ways, applying coupon codes and giving you rewards points that you can use toward perks like gift cards. Best of all, Wikibuy is completely free to use.

Product Features

Wikibuy has plenty of features to help you save money.

Price Comparison

Once you install Wikibuy on your browser, the app tracks your online shopping. It crowdsources product prices from the millions of Wikibuy users to create a database of the best prices on the internet.

When you search for a product on Amazon, Wikibuy notes the price of that product. If another Wikibuy user has bought the same product from another store, Wikibuy compares the prices and notifies you if it’s cheaper on another site. Because Wikibuy has more than 3 million users, it might have information about dozens of other websites selling that product, letting it direct you to the absolute cheapest option.

Your shopping also helps other Wikibuy users. If you buy something at a great price and another Wikibuyer goes to buy that product, Wikibuy will automatically notify them of the great price you found. You help other shoppers while other shoppers help you.

Automatic Couponing

Online merchants often offer coupon codes that customers can use to save some money on their purchases. The problem is that they often distribute the codes through myriad social media channels, e-mail lists, and other methods. It’s hard to find the coupon codes and often, they don’t work, meaning you’ve wasted time finding and inputting the codes.

Wikibuy keeps track of the coupon codes that Wikibuyers have successfully used and automatically inputs them for you. If one or more of the codes works, Wikibuy automatically uses the one that will save you the most money.

Price Drop Notification

Wikibuy keeps track of the things you look at or purchase online. If the price on a product drops, Wikibuy lets you know so that you can jump on the deal.

Even if you’ve already purchased the product, some credit cards and merchants offer price protection, meaning you can put some of the money that you spent back in your bank account.


You can link your credit cards with Wikibuy to unlock local offers. Occasionally, Wikibuy will partner with local merchants to give its users rewards when they shop. For example, you might see an offer to get 5% back when you eat at a nearby restaurant. All you have to do is add the offer to your account and pay for the meal with your linked card.

Wikibuy pays those rewards to you in the form of Wikibuy credits, which you can use to buy gift cards to popular stores like Groupon, eBay, or Staples.

Universal Search

If you want to make sure you get the best price on a product, you can search for it directly on Wikibuy’s website. Wikibuy will search its database to find the best vendor and direct you right to the purchase page.

You can also use this feature when you’re shopping in a store. If you download the Wikibuy app to your phone, you can use the phone’s camera to scan a product’s barcode. Wikibuy automatically compares prices from the best online and physical retailers to let you know if you’re getting a good deal.

Pricing and Fees

One of the best things about Wikibuy is that there is no cost to install the app and no fee to use it. It claims that using Wikibuy can help you save money, and there’s no real risk of trying it out because you never have to pay for the service.

Even if you’re skeptical that Wikibuy can help you save, there’s no reason not to give the app a try.

Signing Up

Signing up for Wikibuy is easy. You can start by visiting the Wikibuy website and installing the browser add-on or downloading the app to your phone. Once you’ve done that, you’ll have to provide some basic information:

  • Your name
  • Your zip code (to help it calculate shipping and taxes)
  • Whether you have Amazon Prime (to help it account for shipping times and costs)
  • E-mail address
  • Password

The app will also ask you to enter some of your favorite stores and to provide estimates of your online spending, but you can skip these steps.

Once you’ve done that, which takes less than five minutes, you’re ready to start using Wikibuy.


Wikibuy syncs your data between the phone app and the web browser effectively. You can easily search for items and view your search history through both. The phone app and browser also share a watchlist so you can add items to the list from anywhere.

All you have to do is make sure that you use the same e-mail address and password on each device.


Wikibuy is offered by Capital One, a major bank and credit card provider, so it has some of the latest and most up-to-date security available. While the app does have to track your shopping habits to effectively track the lowest prices for different products, your information is protected by powerful encryption.

Wikibuy does state that it collects and stores the following information on users:

  • User-provided information
  • Cookies and automatically-collected information
  • Location information
  • Payment information
  • Transaction data

If you’re very security and privacy-conscious, it’s worth understanding the information you’re giving up before installing the app.

Mobile Support

Wikibuy has great mobile support. The app is available both through Apple’s App Store and on Google Play, so you can install it on almost any smartphone on the market.

The iOS app has a 4-star rating out of 5 while the Android version has 2.8 stars out of five. Still, both apps are effective and let you search for the best deals, which means you can easily use the service while you’re on the phone.

Support and Customer Service

Wikibuy is a relatively simple application, so it offers bare-bones customer support.

If you have any issues, you can visit the app’s knowledge base to get answers to frequently asked questions. If you need further assistance, you’ll have to e-mail the Wikibuy support team. There is no option for phone or live chat support.
