Chrome Extensions to Save Money While Shopping
Every online purchase is an opportunity to save money—if you have the right tools. Chrome extensions can automatically apply coupon codes at checkout, track price history so you know if a deal is real, alert you to price drops, and earn cashback on purchases you were going to make anyway. Here is our breakdown of the best money-saving extensions for 2025.
Automatic Coupon Finders
Honey (PayPal Honey)
Honey is the most well-known coupon extension, now owned by PayPal. When you reach a checkout page, Honey automatically tests available coupon codes and applies the one that saves you the most. It works on over 30,000 merchant sites and requires zero effort on your part.
Honey also includes Droplist, which tracks prices on Amazon and notifies you when items drop below your target price. And its Honey Gold rewards program gives you points redeemable for gift cards at participating retailers.
Pros: Fully automatic, huge merchant database, price tracking, cashback rewards.
Cons: Owned by PayPal (data privacy considerations), does not always find the best code, some merchants have stopped supporting it.
Capital One Shopping (formerly Wikibuy)
Capital One Shopping searches for coupon codes and also compares prices across multiple retailers. If another store has the same product for less (including shipping), it alerts you. You do not need to be a Capital One customer to use it.
Pros: Price comparison across retailers, automatic coupon testing, cashback credits.
Cons: Backed by a financial institution (data collection concerns), notification frequency can feel aggressive.
Coupons at Checkout by RetailMeNot
RetailMeNot's extension works similarly to Honey, automatically surfacing and applying coupon codes at checkout. It draws from RetailMeNot's large coupon database and also shows cashback offers from participating merchants.
Price Tracking and History
Keepa — Amazon Price Tracker
Keepa is essential for Amazon shoppers. It embeds a detailed price history chart directly on Amazon product pages, showing you the price trend over days, weeks, months, or years. You can immediately tell if a "sale" is a genuine discount or if the price was just inflated before being "reduced." You can also set price alerts to get notified when an item drops to your target price.
Pros: Detailed historical charts, price drop alerts, works internationally, reveals fake deals.
Cons: Amazon only, chart can be overwhelming at first glance.
CamelCamelCamel
The Camelizer (CamelCamelCamel's Chrome extension) shows Amazon price history with a simpler interface than Keepa. It tracks three price types: Amazon direct, third-party new, and third-party used. Price alerts notify you via email when prices drop.
Pros: Clean interface, three price types, email alerts, trusted long-running service.
Cons: Amazon only, fewer data points than Keepa, no in-page chart.
Cashback Extensions
Rakuten (formerly Ebates)
Rakuten is the largest cashback platform, offering between 1 and 15 percent cashback at thousands of stores. The Chrome extension notifies you when you visit a participating store and activates cashback with one click. Rakuten pays out quarterly via check or PayPal.
Pros: High cashback rates, huge store network, reliable payouts, stacks with coupon codes.
Cons: Quarterly payouts (not instant), requires clicking to activate, some stores excluded.
TopCashback
TopCashback often offers higher cashback rates than Rakuten for the same stores. It is worth having both installed and comparing rates before making large purchases. The extension activates cashback automatically when it detects a supported merchant.

Privacy Considerations
Money-saving extensions work by monitoring your shopping activity—that is how they know when to show coupons or activate cashback. This means they see the sites you visit and the products you browse. Consider these factors:
- Read the privacy policy: Understand what data is collected, how it is used, and whether it is shared with third parties.
- Use selectively: You can disable extensions when not shopping and enable them only at checkout.
- Avoid stacking too many: Running three coupon extensions simultaneously can cause conflicts and slow down checkout pages.
