Chrome Extensions That Save You Money While Shopping Online

Smart shoppers know that the sticker price is rarely the final price. The right Chrome extensions for online shopping automatically find coupon codes, compare prices across dozens of retailers, and even earn you cash back — all without any extra effort on your part. Here's how to build the perfect money-saving browser setup.

The Core Money-Saving Stack

You don't need every extension on this list — but having one coupon finder, one price comparison tool, and one cash-back extension running together can save you 10–30% on most purchases. The best part: they all run automatically in the background.

1. Honey — Automatic Coupon Codes

Honey is the most popular shopping Chrome extension, used by over 17 million shoppers. When you reach the checkout page of any supported retailer, Honey automatically tries thousands of coupon codes and applies the best discount it finds. Honey Gold rewards points are earned on purchases and redeemable for gift cards. It works on Amazon, Walmart, Target, Nike, ASOS, and thousands more stores.

How Honey Works at Checkout

You fill your cart and reach the checkout page
Honey detects the checkout form and shows an activation button
Click "Apply Coupons" — Honey tests available codes automatically
The best code is applied and your savings are shown

2. Rakuten — Cash Back on Every Purchase

Rakuten (formerly Ebates) partners with over 3,500 retailers to offer cash back on purchases. The Chrome extension activates automatically when you visit a partner retailer and prompts you to turn on cash back. Rates range from 1% to 15%+ depending on the store and current promotions. Earnings are paid quarterly via PayPal or check.

3. Capital One Shopping — Real-Time Price Comparison

Capital One Shopping does something Honey doesn't: it compares prices in real time. As you browse Amazon, it checks the same product on Walmart, Target, Best Buy, and other retailers and shows you if there's a lower price elsewhere. It also applies coupons automatically. No Capital One account required.

4. CamelCamelCamel — Amazon Price History

Before buying anything on Amazon, it's worth checking whether the price is genuinely good. CamelCamelCamel shows a full price history graph for any Amazon product, revealing the all-time low, average price, and whether the current price is inflated. This is especially important around sales events when Amazon sometimes raises prices before applying a "discount."

5. Keepa — Amazon Price Tracker

Keepa embeds a price history chart directly on Amazon product pages — you don't need to visit a separate website. It also lets you set price drop alerts: enter a target price and Keepa emails you when the item drops to that level. Keepa's data goes back further than CamelCamelCamel and covers more Amazon marketplaces worldwide.

6. Coupert — Coupon Codes + Cash Back

Coupert combines coupon code discovery with a cash-back program similar to Rakuten. It shows a notification when you visit a supported store, and applies coupon codes automatically like Honey. The cash-back feature is newer than Rakuten's but the coupon detection is competitive. A good alternative if you want one extension doing both jobs.

7. RetailMeNot Deal Finder

RetailMeNot has one of the largest coupon databases on the internet, and its Chrome extension surfaces deals as you shop. It's particularly strong for in-store deals and restaurant discounts in addition to online coupons — useful if you shop at both physical and online retail locations.

Stacking Strategies

Best for Amazon: Keepa (price history) + Capital One Shopping (price comparison) + Honey (coupons)
Best for general retail: Honey (coupons) + Rakuten (cash back)
Privacy-conscious option: PriceBlink (comparison only, minimal data collection)

Conclusion

Installing Honey, Rakuten, and CamelCamelCamel takes under five minutes and can save you meaningfully on every online purchase you make this year. Explore these and hundreds of other useful extensions in the Unscart directory.
