How fresh are the listings?
Listings are re-collected on a schedule and each one carries the time it was last seen. Availability and price should always be confirmed on the original source, which we link from every listing.
Any aggregator is a snapshot: a listing can be withdrawn or its price changed between our collection and your reading. This is why we treat the source as authoritative rather than caching a price and presenting it as current, and why every listing links back to where it came from.
