Browser Extensions — The Five-Tool Stack
The extensions that most active deal hunters install once and use on every purchase:
1. Honey — auto-coupon at checkout. Install this first.
2. Keepa (or CamelCamelCamel) — Amazon price history embedded in product pages. Keepa shows the chart without leaving Amazon; CamelCamelCamel is free and excellent for occasional checks.
3. TopCashback button — activates cashback automatically when you visit a participating retailer. Ensures you never forget to activate.
4. Google Shopping sidebar — appears when you search products; provides quick price comparisons across retailers without extra steps.
5. Privacy.com or Revolut virtual cards — generate one-time or merchant-locked virtual card numbers for subscriptions. Prevents unwanted renewals and makes subscription cancellation instant by simply deleting the virtual card.
