The Best Browser Extensions for Automatic Discount Codes in 2025

Online shopping is convenient — but saving money while doing it is even better. These browser extensions do the heavy lifting by finding and applying coupon codes automatically, so you never miss a deal again.

Why Use a Discount Extension?

Discount extensions have become essential tools for savvy online shoppers. They scan the internet for active promo codes, test them at checkout, and apply the best one — saving both time and money. Some also offer cashback or rewards, making them even more valuable.

1. Honey

Platform: Chrome, Firefox, Safari, Edge
Pros: Automatic coupon application, Honey Gold rewards system, Amazon price tracking
Cons: Can occasionally miss niche site deals

Honey, owned by PayPal, is one of the most popular and trusted coupon extensions. With a single click, it tests multiple codes and applies the best one at checkout. Users can also earn Honey Gold, which can be redeemed for gift cards.

2. Capital One Shopping

Platform: Chrome, Firefox, Edge, Safari
Pros: Price comparison tool, coupon application, rewards
Cons: Requires account setup, price comparisons sometimes inaccurate

Formerly known as Wikibuy, Capital One Shopping helps users compare prices from different sellers and apply coupons. It also offers a rewards program for select purchases. While it works independently of Capital One banking, an account is required.

3. Rakuten

Platform: Chrome, Firefox, Safari, Edge
Pros: Cashback on purchases, applies coupons, well-established brand
Cons: Less focused on coupon variety compared to others

Rakuten specializes in cashback offers, partnering with thousands of stores. The extension alerts users when cashback is available and also tries coupon codes automatically. While its coupon selection isn’t as robust, the cashback feature makes up for it.

4. RetailMeNot Deal Finder

Platform: Chrome, Safari, Firefox
Pros: Reliable coupon database, quick interface
Cons: Fewer cashback features

RetailMeNot’s Deal Finder is an underrated option. It taps into the platform’s vast database of coupon codes and tests them quickly at checkout. It doesn’t offer rewards or cashback, but is lightweight and efficient for deal-finding.

5. Coupert

Platform: Chrome, Firefox, Edge, Safari
Pros: Real-time working code detection, cashback, multi-country support
Cons: Less known, can be inconsistent on smaller sites

Coupert is gaining traction for its real-time coupon updates and cashback offerings. It supports a wide range of countries, making it great for international users. The extension detects discounts actively used by other shoppers, increasing reliability.

6. Honey vs. Capital One Shopping: Which Is Better?

Both are industry leaders, but they serve slightly different purposes. Honey is better for coupon code hunting and has a sleek UI, while Capital One Shopping shines in price comparisons and broad store support. Trying both is often the best strategy — they won’t interfere with each other.

Tips for Using Discount Extensions

• Enable notifications: Many extensions will alert you to deals on visited product pages.
• Stack rewards: Some extensions allow stacking coupon savings with cashback rewards.
• Create accounts: Certain features like price tracking or rewards may require login.

Conclusion: Automate Your Savings

With so many browser extensions available, there’s no excuse to pay full price when shopping online. Whether you’re after cashback, coupon codes, or smarter price comparisons, tools like Honey, Rakuten, and Capital One Shopping help maximize your savings with minimal effort.
