Let Technology Do the Discount Hunting for You
You don't have to manually search for coupon codes or compare prices across tabs anymore. A handful of free browser extensions can do that work silently in the background, stepping in at checkout to apply savings you might have missed. Here's a breakdown of the most useful ones and what each does best.
1. Honey (by PayPal)
Honey is probably the most well-known shopping extension. When you reach a checkout page, it automatically tests available coupon codes and applies the one that saves you the most. It also shows you a price history chart for Amazon products and lets you create a wishlist that alerts you to price drops.
Best for: Coupon code automation and Amazon price tracking.
2. Capital One Shopping
Similar to Honey, Capital One Shopping tests coupon codes at checkout and alerts you if the item you're viewing is available cheaper at another retailer. You don't need to be a Capital One customer to use it — it's a free tool open to everyone.
Best for: Price comparison alerts across retailers.
3. Rakuten
Rakuten is primarily a cashback portal, but its browser extension notifies you whenever you land on a participating retailer's site, making it easy to activate cashback with one click. Earnings are paid out quarterly as a check or PayPal payment.
Best for: Earning cashback at hundreds of major retailers automatically.
4. CamelCamelCamel (via Camelizer)
The Camelizer extension adds an Amazon price history chart directly to any Amazon product page. This is invaluable for understanding whether a "sale" price is genuinely low or just a normal fluctuation. You can also set target price alerts.
Best for: Verifying Amazon deal legitimacy with price history data.
5. Wikibuy (now Capital One Shopping)
Now merged into Capital One Shopping, this extension's core feature remains strong: it scans for the same product at lower prices across other online stores while you shop, displaying a small badge when it finds something cheaper.
6. Invisible Hand
InvisibleHand is a lightweight extension that displays a small notification bar when it finds the product you're viewing at a lower price on another site. It covers a wide range of retailers including flights and hotels, making it useful beyond standard shopping.
Best for: Shoppers who browse multiple categories including travel.
7. PayPal Honey (Gold) Rewards
Beyond coupon codes, Honey's Gold program lets you earn points (called Gold) on purchases from participating stores, which can be redeemed for gift cards. It's an additional layer of rewards on top of any sale prices or codes already applied.
How to Use These Extensions Together
You don't have to choose just one. Many shoppers run two or three simultaneously. A common combination:
- Rakuten for cashback activation
- Honey for automatic coupon codes
- Camelizer for Amazon price history verification
Together, these three tools cover coupon hunting, cashback earning, and price verification — the three pillars of smart online shopping — without requiring any extra effort on your part.
A Quick Note on Privacy
Shopping extensions do read your browsing activity on retail sites in order to function. If privacy is a concern, review each extension's privacy policy and consider only installing the ones you'll actively use. Stick to well-known, reputable tools and check their permissions before installing.
