Browser Extensions That Save You Money While You Shop

Most people know these tools exist. Far fewer have them installed. That gap is doing real damage to their wallets.

Browser extensions that help you save money while shopping are true set-it-and-forget-it tools. You install them once, they work in the background, and you start spending less without changing how you shop. Here’s what they do and which ones are worth having.

How Shopping Browser Extensions Work

Shopping extensions sit in your browser and activate automatically when you land on a retail site. Depending on the tool, they can:

• Find and apply coupon codes at checkout so you’re not copying and pasting from coupon sites
• Alert you to lower prices on the same item at competing retailers
• Track price history on products you’re viewing so you know if you’re seeing a real deal
• Add cash back to purchases at participating stores

Most of them are free. They make money by earning referral commissions when you buy through them, which doesn’t cost you anything.

The Extensions Worth Installing

💰 Honey (by PayPal)

Honey is probably the most well-known shopping extension. When you land on a checkout page, it automatically searches for working coupon codes and applies the best one. It also has a feature called Droplist, where you can save Amazon products and get notified when the price drops to your target.

The Gold program rewards you with Honey Gold points on purchases at participating stores, which you can redeem for gift cards.

Best for: Coupon code hunting at checkout, Amazon price drop alerts. Learn more at joinhoney.com

💸 Rakuten (formerly Ebates)

Rakuten gives you cash back at over 3,500 stores. When you click the Rakuten button in your browser before checking out, it activates cash back on your purchase. The cash gets deposited to your account quarterly.

The rates vary by store and season, but it’s common to see 3-10% back at stores like Macy’s, Walmart, Target, Nike, and Sephora. Rakuten also runs limited-time double cash back promotions that can make the savings significant.

This is one I personally use on every major purchase. If you’re not signed up yet, you can get a cash bonus when you join through a referral link.

Best for: Cash back on everyday purchases at major retailers.

🔍 Capital One Shopping (formerly Wikibuy)

Capital One Shopping does a few things at once. It compares prices across retailers when you’re looking at a product, hunts for coupon codes at checkout, and shows you price history on Amazon. You don’t need a Capital One account to use it.

The price comparison feature is especially useful if you’re buying something that’s available in multiple places. It surfaces cheaper alternatives automatically.

Best for: Price comparison, Amazon price history, coupon codes. Learn more at capitaloneshopping.com

📊 CamelCamelCamel (Amazon-specific)

CamelCamelCamel isn’t an extension in the traditional sense, but they have a browser button called The Camelizer that shows you a full price history chart for any Amazon product you’re looking at. This is the most important tool for Amazon shopping.

When a product is marked “on sale” on Amazon, the price history tells you whether that’s real. Some products fluctuate constantly and the “sale price” is the regular price half the time. Others show a genuine all-time low.

You can also set price alerts through the CamelCamelCamel website to get emailed when a specific product hits your target price.

Best for: Verifying whether an Amazon deal is real, price drop alerts. Install The Camelizer at camelcamelcamel.com

🏷️ RetailMeNot Deal Finder

RetailMeNot is a long-standing coupon aggregator with a browser extension that works similarly to Honey. When you’re checking out, it searches its database for applicable coupon codes. It also shows available cash back offers at certain stores.

Best for: Coupon codes at a wider range of smaller and niche retailers that Honey may not cover as thoroughly. Learn more at retailmenot.com

Which Ones Are Worth Installing?

You don’t need all of them. A few will cover most situations:

The core three: Rakuten, Honey, and CamelCamelCamel. Between these three, you’re getting cash back, coupon codes, and price verification on Amazon.

If you’re an Amazon-heavy shopper: Add Capital One Shopping specifically for the Amazon price history and price comparison features.

If you shop a lot of smaller retailers: Add RetailMeNot to catch codes that Honey might miss.

The extensions don’t conflict with each other, so having all five running at once isn’t a problem. But if you only do one thing today, install Rakuten. Cash back is the most straightforward form of savings, and it adds up faster than you’d expect.

One Thing to Know About Coupon Extensions

Not every code these tools find will work. Coupon databases go stale, and some codes are only valid for new customers or specific accounts. The extensions will try multiple codes automatically and apply the best one, but occasionally you’ll land on a checkout with no working codes. That’s normal.

The cash back features (Rakuten, Honey Gold) are more reliable since they’re tied to affiliate tracking and don’t depend on coupon validity.

These tools take about five minutes to set up total, and they work on every shopping trip you take after that. It’s a rare category of thing where the effort-to-reward ratio is almost absurdly good.
