I suffer from a common shopper’s conundrum: I love saving money, but I hate shopping around for the best deal.

In the past, every time I would get ready to check out online, I’d open a new tab and type “[SITE NAME] coupon codes” into Google. Sometimes I’d search through pages of deals only to find that none of them worked.

Eventually, I stopped trying. But then every purchase came with a twinge of guilt because, I thought, “I could be spending more money than I need to. What if there’s a deal I don’t know about?”

That’s why when I heard of Wikibuy in 2017, I immediately looked it up and added the browser extension. I was beyond excited for a tool that could help me save money with little to no effort on my part.

Like any app, Wikibuy has its pros and cons. But more than three years later, it’s still the online shopping companion I rely on the most.

What is Wikibuy?

In short, Wikibuy is a free coupon and rewards app. It comes in two primary forms: a browser extension (available for Google Chrome, Safari, Mozilla Firefox, and Microsoft Edge), and a mobile app.

The Austin, TX-based company was founded in 2014 and acquired by Capital One in 2018. Wikibuy currently has millions of members who, according to the site, have collectively saved over $50 million using the tool.

Is Wikibuy Safe?

Wikibuy was trusted by hundreds of thousands of users before 2017, but its membership has grown significantly over the last few years.

The browser extension, like similar programs, will collect data on your search and shopping history as well as personal and non-personal information. According to their privacy policy, that includes your:

  • User-provided information,
  • Retail account log-in credentials,
  • Social media data,
  • Payment information,
  • Transaction data,

as well as other information.

But according to Capital One’s Opt Out Privacy Notice, they don’t share your information for other affiliate or non-affiliate companies to market to you. In other words, you won’t have to worry about signing up for Wikibuy and suddenly being bombarded with marketing emails from companies you’ve never heard of.

Wikibuy also has a strong rating on Trustpilot of 4.6 out of 5 stars and an A- rating with the Better Business Bureau. All in all, these are strong indicators that Wikibuy is a safe and trustworthy tool.

How Does Wikibuy Work?

Wikibuy comes with several handy features, including Amazon price comparison, automatic coupons, and rewards credits for online shopping.

Receive automatic rewards and coupons

The easiest and probably the most common way to use Wikibuy is for automatic coupons and gift card credits. You’ll need to add the browser extension in order to access this feature.

Once you have the extension, any time you’re shopping on a site that offers coupons or credits with Wikibuy, you’ll get a helpful pop-up notification at checkout.

When I was shopping for groceries and makeup on Vitacost, Wikibuy offered me 1% rewards credit and found 10 coupon codes to try out.

When you click the button for coupons, Wikibuy will scan through each one automatically to see which gives you the best deal.

Once the coupon or credit is applied, you’ll get another friendly pop-up that tells you whether or not any of the coupons worked, how much you saved, and when your credit will be available in your Wikibuy account.

Wikibuy savings on Vitacost

Reviewer’s take: This is the Wikibuy feature that I use most often. I love that it’s zero effort on my part. I tend to forget that I have Wikibuy until I get one of these notifications at checkout letting me know there’s money to be saved. If you’re all about taking the path of least resistance to save money, then this will probably be your favorite feature, too.

Get a lower price on Amazon

This Amazon-specific feature searches the web to make sure you’re getting a good deal or if another merchant or site has a better price.

When you’re shopping on Amazon and click on an item, you’ll see a Wikibuy button under the price that indicates whether or not there is a better price available for that product. If another merchant or retailer is selling the same item for less, then you’ll see a green Wikibuy button with the amount you can save elsewhere.

When you click it, the button will redirect you to Wikibuy’s site where you can see the offer and claim your savings.

Reviewer’s take: This feature is great when it works. However, sometimes Wikibuy misses a beat. It may direct you to the homepage of a seller if the deal has expired, which can be confusing. Or sometimes you’ll find that the item is out of stock with the other merchant.

If something like this happens, you can let Wikibuy know back on the site. When you click the green button on Wikibuy to claim your deal, you’ll get a helpful pop-up that asks “Was this a good result?” Even if you didn’t get the deal you expected, you can inform Wikibuy and help improve the experience for the next user.

View your watchlist for price drops

This is another Amazon-specific feature. If you’ve found an item you like with a price you don’t, you can click the white “W+” button to add it to your watchlist.

Adding item to watch list with Wikibuy

Wikibuy will track the price for that item — on Amazon and at other retailers — for 60 days and let you know if the price drops or if it finds a better deal.

Wikibuy also tracks your history for products you view across multiple sites. At any time, you can visit your watchlist in your account to see if the price has dropped on any of your recently-viewed items. You can clear your history under Account Settings > Clear my product history.

Reviewer’s take: I’ve found the watchlist feature very useful, especially if you’re shopping for something you don’t need right away. For example, if I’m browsing and I find something that would make a great Christmas or birthday present for someone, then I’ll add it to my watchlist and buy it when the price drops.

You can also click the Wikibuy extension icon in your browser to view the product’s price history for up to the last 365 days.

Redeem Wikibuy credits for gift cards

Whenever you redeem an offer with Wikibuy, it’ll show up as a “credit” in your account. So if you make a $100 purchase with 5% reward, you’ll receive $5 in Wikibuy credit. For most offers, you’ll see your rewards within 7 days.

You can redeem your credit in exchange for gift cards to places like Walmart, Lowe’s, Sephora, and Wayfair. Some gift cards start at $5, but others require a minimum of $10 or $25 to cash out.

Redeeming Wikibuy Credits

Reviewer’s take: While Wikibuy offers a good selection of gift cards, it’s missing some key features that similar sites have. For one, you’re not able to sort gift cards by cash-out amount. The only way to see how much credit you need to redeem a gift card is to click on each individual retailer.

Secondly, though the options are good, they’re fairly limited. While other rewards sites offer gift cards to dozens or even hundreds of retailers, Wikibuy currently has around 37 options, and Amazon isn’t one of them.

Other Wikibuy Features

You may not use these features as often, but they’re convenient when you do.

Product search

If you already know what you want to buy, you can search for it directly on Wikibuy or by clicking the browser extension and typing in the search box.

Searching Wikibuy for products

Your search will take you to Wikibuy’s website where you can filter options by price and brand. The search feature also works on mobile, which is debatably more convenient than the online search tool. If you’re already shopping in-store, use the Wikibuy app on your phone to scan the barcode. Wikibuy will search other retailers and let you know if there’s a better price available.

Reviewer’s take: This feature is especially useful if you’re shopping in-store or if you already know the specific item you want and you’re looking for a low price. It’s less practical if you’re browsing and need to filter by style, color, size, or material, as these sorting options aren’t available on Wikibuy.

I rarely use this feature myself, mostly because I rarely know exactly what I’m looking for until I find it. And at that point, I either use Wikibuy to look for coupon codes or add it to my watchlist.

Featured offers

When you log in to your Wikibuy account, you’ll see featured and trending deals from some of Wikibuy’s most popular retailers.

Wikibuy featured offers on dashboard

Reviewer’s take: I don’t pay much attention to this section myself. You probably won’t do much shopping directly from your Wikibuy dashboard, but it’s a convenient way to explore deals and discover new brands.

Local deals

Shopping online isn’t the only way to save money with Wikibuy. On the dashboard of your account, if you scroll past the featured and trending deals, you’ll see a “Local Offers” section. You can earn 4% or more in loyalty credits for shopping at local businesses.

In order to take advantage of local deals, you’ll need to link your credit or debit card to your Wikibuy account. Whenever you make a qualifying purchase at participating local retailers, you’ll receive an automatic credit, similar to shopping online with Wikibuy; you can exchange your credits for gift cards through your Wikibuy portal.

Reviewer’s take: Depending on your location, there might not be many local deals available. I live in a college town and there are only two restaurants in my “local deals,” neither of which I’m familiar with.

Mobile price comparison

If you’re shopping on Amazon from your phone and need a price check, you can text the product to Wikibuy. They’ll send you a text back with a link to compare prices at other retailers.

Reviewer’s take: Admittedly, this feature is a little clunky. Wikibuy’s price comparison tools work best on a desktop, but if you’re on the go and need to compare prices quickly, it can come in handy.

Who Should Use Wikibuy?

As a Wikibuy user since 2017, I don’t see myself moving away from the platform any time soon. It’s an easy, low-effort way to save money on the things I’d be buying anyway, like makeup from Vitacost or a rug on The money I save with Wikibuy is money I know I wouldn’t have saved otherwise, because I don’t like manually searching a hundred sites for a coupon code that works.

If you’re someone like me who loves the idea of saving money but doesn’t want to search every site looking for a good deal, then Wikibuy is probably a good fit for you. With Wikibuy, there’s no searching, just saving.
