What "prices updated daily" actually means

A sentence like "prices are updated daily" sounds like an absolute promise, and it is not. It is worth knowing exactly what sits behind it, because that is what decides when you can trust a number and when to check again.
Where the number comes from
Israel's price-transparency law requires the large retail chains to publish full price files every day — for every branch and every product. We collect those files, consolidate them by barcode, and present them in one place.
What that means: the price you see is not our estimate, not a sample and not an average. It is the last price the chain itself officially declared for that branch.
What it does guarantee
That comparison between chains is fair: everyone reports under the same obligation, in the same format, against the same barcodes. When we say chain A is cheaper than chain B on a product, that rests on their own declarations.
And that the picture is wide: in one measurement of a single product on 13 August 2026 there were 716 active prices across 29 chains. No shopper can gather that much data alone, and that is precisely the advantage.
What it does not guarantee
That this will be exactly the price at the till. Three main reasons: a club or membership price that is not part of the published price, a promotion that started or ended between publication and your shop, and a gap between what the chain published and what the shelf actually says.
Also: a price that has not changed is not necessarily "old". A stable product can hold the same price for weeks, and that is correct. Lack of movement is not a sign of stale data.
How to use it properly
Treat a price as an input to a decision, not as a contract. It is excellent for answering "where is this worth buying" and "is this promotion actually cheap" — two questions asked before you leave the house.
At the till, a glance is worth it. If there is a large, unexplained gap, it is worth raising with the branch — and worth telling us, because that is how genuine data faults get found.
The simple rule Trust the gap, not the last shekel. If a product is 30% cheaper at another chain, that gap is real even if the exact price shifts a little. If the difference is 20 agorot, it was never a story.
In one line
We show what the chains officially published, daily, per branch. That makes comparison between chains trustworthy — and it does not replace a quick look at the receipt.
