Let Your Browser Do the Bargain Hunting
You don't have to spend hours searching for coupon codes or comparing prices manually. A handful of free browser extensions will do that work automatically — finding discounts, tracking price history, and alerting you when something drops in price. Here are 10 worth installing today.
1. Honey (by PayPal)
Honey is one of the most popular shopping extensions available. When you reach checkout on thousands of supported sites, it automatically tests available coupon codes and applies the best one. It also has a feature called Droplist that alerts you when a product on your wishlist drops to your target price.
Best for: Coupon code automation | Available on: Chrome, Firefox, Edge, Safari
2. Capital One Shopping
Similar to Honey, Capital One Shopping applies coupon codes at checkout and compares prices across retailers. You don't need a Capital One account to use it. It also shows you lower prices on the same product at competing stores in real time.
Best for: Price comparison + coupon codes | Available on: Chrome, Firefox, Edge
3. CamelCamelCamel / Keepa
Both of these extensions add price history charts directly to Amazon product pages. This is crucial because "sale" prices on Amazon aren't always as good as they look. A quick glance at the chart tells you if the current price is genuinely a deal or close to the historical average.
Best for: Amazon price history | Available on: Chrome, Firefox
4. Rakuten (formerly Ebates)
Rakuten offers cash back on purchases at thousands of stores. When you shop through Rakuten-supported sites, you earn a percentage back as real money (paid via PayPal or check). The extension activates automatically when you visit a participating retailer.
Best for: Cash back rewards | Available on: Chrome, Firefox, Edge, Safari
5. PayPal Honey's Price History Tool
Beyond coupon codes, Honey's Gold feature lets you earn points (called Gold) on purchases at select stores. These points can be redeemed for gift cards. It's a passive way to stack rewards on top of regular shopping.
6. PriceBlink
PriceBlink shows you if the product you're viewing is available cheaper elsewhere — right on the page you're already browsing. It scans hundreds of retailers and displays comparison prices without you having to open a new tab.
Best for: Instant price comparison | Available on: Chrome, Firefox
7. InvisibleHand
InvisibleHand quietly monitors your browsing and notifies you with a small banner when it finds a lower price for the same product or travel booking elsewhere. It covers retail shopping, flights, hotels, and rental cars.
Best for: Travel + retail price alerts | Available on: Chrome, Firefox
8. Wikibuy (Capital One Shopping)
Now merged into the Capital One Shopping experience, Wikibuy's core function was spotting better prices and applying coupons automatically. The combined tool remains one of the most thorough price-checking extensions available.
9. DealNews Extension
DealNews curates editorially-reviewed deals and this extension notifies you when a particularly strong deal goes live in a category you care about. Great for staying on top of flash sales without constantly refreshing deal sites.
Best for: Deal discovery | Available on: Chrome
10. Karma (Shop)
Karma lets you save items you're considering buying and monitors them for price drops. When a price changes or a coupon becomes available, it notifies you. It also applies coupons automatically at checkout on supported stores.
Best for: Wishlist tracking + alerts | Available on: Chrome, Firefox, Safari
A Few Tips for Using These Extensions
- You don't need all 10. Pick 2–3 that cover different functions (e.g., one for coupons, one for price history, one for cash back).
- Be aware that some extensions collect browsing data — review privacy policies before installing.
- Stacking tools (e.g., using Rakuten for cash back and Honey for a coupon code at the same checkout) can compound your savings.
A few minutes of setup today can translate into meaningful savings on every purchase you make going forward.
