You are already leaving money on the table every time you check out online without one of these tools in your browser. The question is, which one is actually worth installing?
Three free browser extensions dominate the online shopping savings space right now: Honey, Capital One Shopping, and RetailMeNot. Each one promises to find you discounts automatically. But they work very differently, and stacking the wrong one with your shopping habits could mean missing out on serious savings. We tested all three. Here is exactly what you need to know.
| Quick StatsHoney users save an average of $126 per year according to the platformRetailMeNot has paid shoppers over $85 million in cashback to dateCapital One Shopping compares prices across tens of thousands of retailers automaticallyAll three extensions are completely free to install and useTime to install each: under 2 minutes |
1. Honey: The Speed Champion of Coupon Hunting
Owned by PayPal and available at over 40,000 online stores, Honey is the extension most people have heard of. Its core job is simple: test every available coupon code at checkout so you never pay full price by accident.
How it works: You shop as normal. When you hit the checkout page, Honey pops up and runs through its entire database of codes in about 30 seconds. It then applies the biggest discount automatically. No copying and pasting. No hunting through expired codes on random websites.
What Honey Does Best
- Applies coupons automatically on major retailers including Amazon, Target, Walmart, and Nike
- Honey Gold rewards program lets you earn points redeemable for gift cards
- Droplist feature tracks price drops on saved items and alerts you when to buy
- Works on Chrome, Firefox, Safari, Edge, and Opera
- Historical price charts help you spot real deals vs. inflated ‘sale’ prices
One key advantage: Honey is fastest at code application. If you shop heavily on Amazon and want coupon speed, this is your go-to. The catch? Cashback rewards come in the form of Honey Gold points, not actual cash. To get value, you need to redeem them for gift cards.
Action: Add Honey to your browser for free at joinhoney.com and run it on your next checkout to see savings instantly.
2. Capital One Shopping: The Price Comparison Powerhouse
Capital One Shopping (formerly Wikibuy) does something the others do not do nearly as well: it tells you when the exact product you are looking at is cheaper somewhere else. That is a game-changer for anyone who defaults to buying on Amazon or Target without checking around.
Here is the magic: while you browse a product on Amazon, Capital One Shopping quietly checks other retailers in real time. If it finds the same item cheaper at Walmart, Costco, or another store, a green button pops up with the savings amount. You do not need a Capital One credit card to use it. It is free for everyone.
What Capital One Shopping Does Best
- Cross-retailer price comparison that factors in tax and shipping
- Automatic coupon code application at checkout
- Universal Product Search for scanning barcodes in-store via the mobile app
- Price drop alerts on tracked items
- Works on Chrome and Edge
The downside: rewards come as Capital One Shopping credits, redeemable only for gift cards at select retailers. If you want actual cashback, this is not your primary earner. But as a savings alert tool, it is exceptional.
Action: Install free at capitalone.com/shopping and let it run on your next Amazon session to see how often you are overpaying.
3. RetailMeNot: The Only One That Pays You Real Cash
Here is where RetailMeNot pulls ahead of the other two: it pays cash back that you can actually withdraw via PayPal or Venmo. No gift cards. No credits. Real money.
The extension works across over 20,000 brands and automatically stacks cash back on top of available coupon codes at checkout. RetailMeNot has paid out over $85 million in cash back to shoppers, and you can earn up to 20% back at select retailers.
What RetailMeNot Does Best
- Real cash back payable through PayPal or Venmo (not gift cards)
- Stackable savings: cash back stacks on top of eligible coupon codes
- Covers tech, fashion, beauty, home essentials, food delivery, and entertainment
- Works on Chrome, Edge, and Firefox
- Covers brands like Target, Sephora, Macy’s, Best Buy, Papa John’s, and DoorDash
The trade-off is that RetailMeNot’s price comparison features are more limited than Capital One Shopping, and its coupon code success rate on smaller retailers is inconsistent. But if the goal is a direct cash payout, this is the only extension in this comparison that delivers.
Action: Install free at retailmenot.com and activate cashback before your next online order.
