Coupon extensions try codes at checkout. Price trackers watch the price over time. Confusing the two is how people end up paying full price with a five per cent code attached and feeling clever about it.
What each one is good at
- A coupon tool works on the price in front of you right now, and typically finds a small percentage — when a valid code exists at all.
- A tracker works on the price you have not seen yet, and the gap between a product's normal and lowest price is usually far larger than any code.
- A coupon tool needs to sit in your browser and see the pages you visit. A tracker does its work while the browser is closed.
The arithmetic
Take a pair of trainers at 179 that clears at 119 once the colourway rotates. Waiting is a saving of 60. A five per cent code applied at full price saves 9, and a ten per cent code saves 18. The timing decision is worth three to six times the code.
The reverse is true only for products that never move — some grocery, some accessories — where a code is the only lever available.
If a product swings twenty-five per cent across the year, no checkout code competes with simply buying it in the right week.
Privacy is part of the comparison
A coupon extension has to read the pages you browse to work. A price tracker only needs the specific product pages you chose to save. That is a meaningful difference in how much of your shopping either tool can see.
Using both, sensibly
There is no conflict: let the alert decide when to buy, and try a code at checkout once you are already there. The order matters — a code applied to a bad price is still a bad price.
Common questions
Do I need to install anything to track prices?
No. Tracking runs on the saved page, not in your browser. The extension on Pro just makes adding products faster.
Does a tracker find coupon codes?
No, and it does not claim to. It watches the price shown on the product page and tells you when it meets your target.
Which saves more over a year?
For anything with seasonal or launch-driven pricing, timing does — usually by a wide margin.
Can I use both at once?
Yes. They act at different moments: one decides when you buy, the other trims the final total.
