Typical-price discount
How far the current signal sits below the trailing 90-day median.
What makes a deal real?
We compare a drop with its own history. A loud discount label alone earns nothing.
Historical-low proximity
How close it is to the lowest observed price in the last year.
Drop momentum
Whether the price moved meaningfully in the most recent 24 hours.
Demand
A normalised popularity signal, without copying customer reviews.
Offer confidence
Data freshness and the reliability of the observed offer.
Freshness
Newer signals rank above stale opportunities.
Explain, don't invent.

No signal is a guarantee.
Prices move, offers end, and product suitability is personal. Every outbound action goes directly to the retailer, where the current terms and price apply.
