If you're on a Galaxy Fold, consider unfolding your phone or viewing it in full screen to best optimize your experience.
Capital One Shopping is the only coupon-rewards app I use. Downloading the free extension has earned me $40 in four months, mostly through sign-up bonuses. My favorite part is you can earn while shopping as usual, no need to shop through a clunky portal. I'll cover when the popular shopping app can save you money, and where it falls short.
Capital One Shopping is a free web browser tool that finds you the best online coupons and prices. Formerly known as Wikibuy, it was purchased by Capital One and rebranded as Capital One Shopping.
The web application searches over 30,000 online retailers to find the best deals. To use Capital One Shopping, download the browser extension (available on Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari) or download the mobile app, available for iOS and Android.
Then, the app can save you money in three ways:
There's no fee to use or install Capital One Shopping. Instead, you give it access to your browsing data. If you're OK with trading data for deals, then it's worth the exchange.
Unlock personalized deals by shopping online as normal, but with the Capital One Shopping extension installed. Personalized deals show you products you viewed and offer you shopping credits for buying them. Think 6% back on a UNIQLO shirt you passed over last week.
The Capital One Shopping extension will show you available coupon codes that could save you money. If you allow it, the extension will attempt to apply all the codes automatically.
You can earn shopping credits through Capital One Shopping. When you visit affiliated retailer websites, you can earn a percentage of your purchase in shopping credits. You can redeem them for gift cards to popular retailers.

All rewards are shopping credits.
If Capital One says you get $60 back on a product, it means you get $60 back you can apply to gift cards through the rewards portal. Kind of misleading, but there you have it. Don't expect cold, hard cash deposited into your checking account.
Capital One Shopping often offers coupon codes that fail to apply.
For example, if the code is for 10% off your order of $50 or more, it won't work if you only have $40 worth of goods in your shopping cart. There are also times when you might run into expired coupon codes. I've had the extension promise me $1 on DoorDash purchases, only to check the app later and find out the rewards were deemed as "invalid." Whomp whomp.
App pop-ups can make shopping more unpleasant.
You'll see Capital One Shopping pop up anywhere that sells merchandise online. Sometimes, you're just window shopping online and don't want extra pop-ups on your screen. It slows things down, and for what? Well, the money, that's what. But it's not always about that.
Capital One Shopping is free to use, regardless of whether you're a Capital One credit card or banking customer. You can download and use the app and web extension for free anytime. Sometimes, Capital One Shopping even pays you for downloading it. I earned $10 for adding the mobile extension and $30 just for signing up.
The Capital One Shopping app has strong mobile reviews, with caveats. Many reviewers confuse the shopping app for Capital One's other services. A fair bit seems spammy, too. The most relevant reviews cite not earning promised payouts, and not actually earning anything through the app.
Capital One Shopping offers a mobile app, a desktop platform, and a browser extension. I use the extension, only navigating to the app and the desktop platform to check rewards (and occasionally, personalized deals).

Capital One Shopping is reasonably safe to use. It doesn't ask you to provide sensitive information, and you can log in with your Google or Capital One account. It does collect a lot of data for its own use, but it doesn't let partners use that data to market their products to you.
If you want an app that earns cash back: Rakuten is a money-saving app that helps you earn cash back for online purchases. Depending on your rewards preference, you may want to stick with Capital One Shopping and redeem rewards for gift cards.
If you want an app that rewards in-person shopping: Fetch is another app that earns rewards, but includes in-person shopping at physical stores. The app lets you scan store receipts and e-receipts to earn valuable rewards you can redeem for gift cards and more. But if you don't shop in person much, Capital One Shopping may be a better choice.
No. Capital One Shopping is available to everyone, including those who don’t have a Capital One credit card or bank account. You can use it by simply downloading the browser extension or the mobile app.
Capital One Shopping is a free browser extension that searches for coupon codes and allows you to earn rewards while shopping online. You can also use the Capital One Shopping website to search for the best deals available.
Most rewards will become available within 30 to 90 days of making a purchase to account for returns, cancellations, adjustments, and exclusions. Travel-related rewards may take up to 90 days after the travel has been completed to post to your account.
