Offers and freshness

Every price comes from a store’s offer, checked at a known time. Here is how to read it.

Lessons · Offers and freshness

Market and snapshot

A market is the offers we track for one category in one country, in that country’s currency, from the stores we track there. We collect them into a snapshot: the products, their offers and the time each offer was checked. Every price you see is the price in that snapshot, with its store and check time.

A price from one market is never used in another. If a product has no Canadian offer, the Canadian market shows none.

Current offers

An offer is current when the store still listed it at our latest check. The market, Compare and Value use only current offers: new ones by default, and refurbished or used ones when you choose them. A product shows its lowest current price (from) and the offers behind it.

The Offers tab with each store offer, its check time and Offer Value, and a Currently unavailable, last seen section
Where to look: each offer shows its store and when it was checked. The cheapest is marked BEST PRICE. Below, Currently unavailable · last seen keeps an offer that has left the store, in grey, with its date.

Last seen offers

When a product’s last offer disappears, its page stays. It shows the last offer we saw, with its date, marked as not current. It does not count toward Value, because a price from weeks ago would make a comparison look better than it is. More in What “no current offer” means.

Freshness

Stores are checked at different times. The market page shows the snapshot date and, under Sources refreshed, each store’s last check. Times are in your own time zone.
