How to find Amazon coupons and price drops in Chrome
Joseph HuLast reviewed September 14, 2026
Quick answer
Clip Amazon's own coupon on the product page first. Then install Keepa to see the price history, and Coupert to test coupon codes and earn cashback at checkout.
Amazon has its own coupons, and most people never notice the checkbox. What Amazon does not do is tell you whether a "deal" is cheaper than last month, or test promo codes for you at checkout. Coupon extensions do the second; a price tracker does the first. Capital One Shopping, the largest coupon extension, left the Chrome Web Store in August 2026, so this page compares the four that remain listed as of September 2026.
Use Amazon's own coupons, deals and price signals
Amazon publishes coupons, lightning deals and Subscribe & Save discounts on the site itself. Checking them takes a minute and needs no extension; it is the baseline any extension has to beat.
- 1On the product page, look under the price for a "Coupon" checkbox and tick it; the discount applies at checkout.
- 2Open amazon.com/coupons and search the category you are buying in, since clipped coupons apply across the store.
- 3Check Today's Deals for the same item, and Subscribe & Save if it is something you buy again; the first delivery is often 5 to 15 percent off.
- 4Before paying, open the "Other sellers" panel and compare the total with shipping, because the featured offer is not always the cheapest.
None of that tells you whether the price is low by the item's own history, and none of it tests the promo codes floating around the web. A price tracker answers the first question; a coupon extension does the second at checkout.
Know whether the price is actually low
A price history chart on the product page turns "20% off" into a fact or a marketing claim. One extension owns this job on Amazon, with alerts when the price drops to your target.
Keepa
Keepa puts a price history chart on every Amazon product page and lets you set an alert for the price you want. It is the default on this page because it answers the question a coupon cannot: whether today's price is a deal at all.

Test coupon codes at checkout and earn cashback
Coupon extensions try the codes they know at checkout and apply the best one, and pay cashback on eligible purchases. Two listed extensions do both; one adds price comparison, the other stays lean.
Coupert
Coupert tests coupon codes at checkout, pays cashback and adds price comparison and price drop alerts, which makes it the broadest coupon extension still listed. It was updated on 11 September 2026.

The listing describes automatic coupon testing at checkout from a database it says adds 90,000 codes a day, cashback on purchases, price comparison and price tracking across 200,000 stores.
- Tests available coupon codes at checkout and applies the best one.
- Cashback on eligible purchases.
- Price comparison and price drop alerts beyond checkout.
Trade-offs
- Coupons and cashback depend on the merchant; Amazon rarely accepts third-party codes.
- Its prompts and popups are busy if you only want coupon testing.
- The store disclosure says it handles website content and browsing activity to work.
Mino
Mino does the coupon job with less around it: an alert when codes are available, one button to test them, cashback at supported stores. It has the highest rating on this page alongside Rakuten.

The listing describes an alert when coupon codes are available for the store you are on, an Apply Coupons button that tests each code and keeps the best, and cashback rewards on purchases.
- Tests coupon codes at checkout and applies the best one.
- Cashback at supported stores.
- Fewer price tools than Coupert, so fewer prompts while browsing.
Trade-offs

- Coupons depend on the merchant; Amazon rarely accepts third-party codes.
Make cashback the main job
If you shop across many US retailers, a cashback network with a payout schedule may matter more than coupon testing. Rakuten is the largest, with the highest rating on this page.
Rakuten
Rakuten makes cashback the centre of the experience, with the largest retailer network of the options here and a payout schedule that has run for years. It is the pick when rewards matter more than coupon testing.
