How verification works

Price history

Every offer we track is checked periodically by an automated job. Each check writes a real, timestamped price snapshot — the chart on every product page is built directly from that snapshot history, not a summary or an estimate. “Low,” “High,” and “Average” are computed from the same snapshots you can see plotted on the chart.

What “Verified” means

We distinguish two levels of freshness, and we never blur them together:

• •Verified — we confirmed both the current price and stock availability directly on the merchant’s own listing.
• •Checked — the offer was polled by our tracker, but we don’t have a full confirmation to back a “Verified” claim yet.

The dashed “VERIFIED” seal you see on some product images only ever appears when there’s a genuine, timestamped verification behind it — never as decoration. The exact relative time (“Verified 3h ago”) is always shown alongside it, so the claim is checkable, not vague.

How the deal score is calculated

Every offer’s deal score is the current price’s percentile within that offer’s own recorded price history — 1.0 means the current price matches the historical low we’ve ever recorded; 0.0 means it matches the historical high. We label a score of 0.66 or above Good deal, 0.33 to 0.66 Fair price, and below 0.33 Wait for a better price. When we don’t have enough history yet to compare against, we don’t guess — the offer lands neutral (Fair) rather than defaulting to Good.

“Price dropped today/this week” and “Matches historical low” badges are derived the same way: by walking the real snapshot history to find the actual point where the price changed, not by reading a single stored “previous price” field, which can go stale.
