What a price tag means here
Short version: the number here is a reading, the listing is the price.
Where the number comes from
Every price on this site is read directly from our own product listing by machine, in one pass, and written to the page with the date of that pass. Nobody types a price here. That removes the most common way a catalogue goes stale — a human updating three pages out of forty.
Why the listing still wins
Prices move between our readings: promotions start, a size sells through, a coupon appears. The stock up tag on every page opens the live listing, and whatever it says at that moment is the real price. If the two disagree, trust the listing and tell us so we can look at the reading.
The date beside the price
That is when we last read it, not when it last changed. A price read four days ago is usually still right; one read four weeks ago is a hint rather than a fact. We rebuild the shelves often enough that most dates stay within days.
Struck-through numbers
Where you see a higher number struck through, that is the reference price shown on the listing at the time of the reading, not a figure we invented. If the listing stops showing one, it disappears from our page at the next build.
Pages without a price
Occasionally an item is clearly in production and on sale, but the listing will not return a price to an automated read. We leave the page up and say the price is not readable rather than guessing. The tag still opens the listing.
