Best ways to track prices and restocks in 2026
There are four ways to do this and they are good at completely different jobs. Answer three questions below and the page will tell you which one fits what you are actually trying to do.
Everyone tells you to track prices. Almost nobody tells you which kind of tracking.
The four methods look interchangeable in a list. They are not.
Here is the thing that makes price tracking annoying. Watching a price and waiting for something to come back in stock feel like the same job, and they are not even close. Prices usually change over time, so hearing about it within a day is fine. Stock comes back all at once and can be gone in an afternoon, so you want to know within minutes. Then there is a third case people rarely plan for: the thing you saw in a post or a screenshot, with no link at all, so a tracker has nothing to watch. Four methods, three different problems. Pick your three answers below and we will tell you which one to use and where it will let you down.

WHERE IT WILL ANNOY YOU
The scoring is ours and it is deliberately simple. See exactly how it decides.
How the picker decides, in full
It is a small scoring table, not a model. Each of the four methods starts at zero. Your three answers add or subtract points, and the highest score wins. The reasons printed in your result are the exact rules that fired, in the order they fired, so you can disagree with any of them.
- What you are tracking. Stock adds points to the shop’s own alert, because the shop knows its stock first. Price adds points to the extension and the tracker, because both are built around price history. Both adds a smaller amount to everything.
- Where you found it. A big shop adds points to extensions and trackers, since that is where their coverage is. A smaller shop takes points away from extensions. A post or a screenshot with no link takes points away from every method that needs a URL, which is three of the four.
- How many things. One thing favours the quick methods. Ten or more adds points to keeping a list and takes them away from anything that arrives as a separate email, because that is the volume at which alerts turn into noise.
- The runner-up is just the second highest score. When two methods are close, the honest answer is usually to use both, and the result says so.
Nothing leaves the page. No account, no submission, no analytics event carrying your answers. The scores are computed in the page and thrown away when you close the tab.

First: what can actually be tracked
People say “track it” and mean at least four different things. Worth separating them, because a tool that nails one of these can be completely useless at the next.
A number that drifts. You want to know when it drops below a figure you picked in advance, and hearing about it a day later is usually fine.
Sold out today, back at some unannounced moment. Late news is worth very little here. This is the one that is a race.
Technically in stock, not in the version you need. Most tools quietly treat the page as one product, so they tell you it is available when your size is not.
Not really a tracking job, and the one that goes wrong most often: remembering what you wanted and where you saw it. No tracker can watch a link you never saved.
The four methods, honestly described
1. The shop’s own alert
The “email me when it is back” box on the product page. It has one big advantage: the shop knows its own stock first, so you will rarely hear sooner anywhere else. The catch is that it goes to every person who signed up at the same second, and you are all reading it at once.
2. A browser extension
Sits in your browser and shows price history on the product page, on the shops it supports. Good at the moment of deciding, because the history is right there while you are looking at the thing. It only knows the shops it was built for, and it only helps when you are already on the page.
3. A tracker app or site
You paste a link, it checks that link, it emails you. Works away from your browser and does not care what device you are on. You are trusting somebody else’s checking schedule, and the alert arrives with no memory of why you wanted the thing.
4. Save it, then ask for a watch
You keep the thing somewhere on purpose, and then you switch on watching for the ones that need it. Slower to set up than clicking a box on a page. It is the one that still works when there is no link, because what you saved was the thing, not the address.
Side by side
| Method | Works where | Can watch | When it fires | Where the thing lives | Biggest weakness |
|---|---|---|---|---|---|
| Shop alert | That one shop | Stock, sometimes price | Same second as everyone else | Nowhere, only the email | Everyone gets it at once, and a shop will not tell you it is cheaper next door |
| Browser extension | Supported shops only | Price and its history | While you are on the page | Inside the extension | On a small shop the history chart often does not appear at all |
| Tracker app or site | Any link it can read | Price, sometimes stock | On its own checking schedule | A list of links | The alert does not include your alternatives or the price you planned to pay |
| Save, then watch | Anywhere, link or not | What you switch on | When the watch you set trips | With everything else you saved | Nothing is automatic. Save something and forget to switch on a watch, and it sits there unwatched. That one is ours |
One weakness belongs to all four. If you get twenty alerts a week, you will stop noticing them, which works out the same as never setting them up.
This table is our own summary of how these four approaches work, not a test of named products. Roundups that do compare individual trackers: Karma, Thunderbit, Bright Data.
Why the number keeps moving in the first place
It helps to know what you are watching. A price online is not a decision someone made once and wrote on a card. Profitero counted Amazon changing prices more than 2.5 million times a day, as reported by Quartz. Walmart and Best Buy each made about 50,000 changes across the whole of November.
So the price you saw was only the price at that moment. That is the entire reason any of this exists.

A sale is a date. A low price is a fact about the whole year.
Which? tracked 175 Black Friday deals across eight UK retailers for a year, from May 2024 to May 2025. Of those 175, 83% cost the same or less at some point outside the sale window, and not one of them hit its lowest price of the year on the day itself. Which is why a tracker set to “tell me when it is discounted” is asking the wrong question. Set it to a number you chose instead.

How to pick the number you are waiting for
Every method above works better once you have a target price. Most people skip this and end up waiting for a feeling instead of a figure. Two ways to get to a number in about a minute:
- The easy yes. Ask what price would make you buy without thinking twice. Headphones at $180 today, and you know $140 would be an instant yes. Your number is $140. It does not matter whether the shop ever gets there, because now the alert has a job.
- The lowest you have seen. If an extension shows you a history, take the lowest price of the last year and add a little. A coat that touched $90 in the January sale is unlikely to hit $70, so set $95 and let it go. Aiming below the yearly low is how people wait forever.
Then check the number is the real number. Delivery, taxes and fees can quietly undo a price drop, so compare what you would actually pay at checkout, not the figure on the label. A 15% discount with $12 delivery on a $60 item is not a 15% discount.
Where each method plugs into the life of a thing you want
Most purchases go through the same five moments. Each method helps at only one or two stages. Match the method to the stage you are in and choosing gets much easier.
Step 1 is highlighted because everything else depends on it, and no tool can do it for you. Step 4 is highlighted because it is the one most people try to solve first.
One case, worked all the way through
You want a jacket. It is a specific size, from a shop nobody has ever heard of, and it sold out while you were thinking about it. What actually works?
- Extension. No use here. Small independent shop, so the price history chart never appears. Rule it out first.
- Tracker app. It can load the page, but a size that is sold out often looks the same to a tracker as a size that is in stock, because the page still exists and the price is still printed on it.
- Shop alert. Yes, and it should be your first click. Pick your size before you sign up, because the alert is usually per size. The shop knows its own stock before anybody else does.
- Save it as well. Because in three months you will remember a green jacket and nothing else. The alert only helps if you still recognise the item when it arrives.
So the answer here is two methods, not one, and they do different halves of the job. The shop tells you when. Your own saved list tells you what and why.
Before you set any of this up, write the price you would pay without thinking twice. A watch without a number is just a way of being interrupted by shops.
Where we come into it
This is normally the paragraph where an article promises software that watches every price for you while you sleep. Ours does not do that by itself, and we would rather say so on the way in than have you find out in three months.
In dEssence you save a thing: a product link, a screenshot, a post, a note about something a friend mentioned. Then, on the items that deserve it, you switch on watching for price or stock yourself. Saving does not start watching. What you get for that extra step is an alert attached to the thing you saved, with your own note about why you wanted it, rather than an email that arrives as a stranger. And when it does arrive, it is a nudge to go and look, not an instruction to buy.
Questions people ask before setting this up
How often does a tracker actually check?
It varies by service and by plan, and plenty of them do not say. If the checking schedule is not written on the page, assume it is slower than you would like. For something that sells out in an afternoon, do not rely on a schedule at all. Use the shop’s own alert.
Do they understand my size or colour?
Often not. Many tools treat one product page as one product, so they see the page is live and the price is printed and call that in stock. If the version you need matters, pick the size on the page before you set anything up, and check the alert mentions it.
Is the price history the price I would have paid?
Not always. A history chart usually follows one version of the item, so it can miss your size or colour entirely. Prices can also differ by country, by account and by device. Treat the chart as the shape of the year rather than a receipt.
How do I judge one service against another?
Four questions get you most of the way, and none of them need a review site. How often does it check? Does it handle sizes and colours? What does it do with your data? And how easily can you turn it off when you are done? A tool that is vague about all four is telling you something.
Pick the method that matches the moment, not the one with the most features.
Stock is a race, so use the shop. Price is a wait, so use a number you chose. And keep the thing itself somewhere, because none of this works on something you have already forgotten.
