How we turn 12 months of prices into one honest verdict
No hype and no invented “was” prices. Every verdict comes from a product’s real selling history — and the math is simple enough to check yourself.
Where the data comes from
We read a product’s daily price history for the last 12 months from Keepa, which tracks Amazon’s real selling prices (the Buy Box) — not the retailer’s inflated “list” price. “Now” is the live Amazon price at the moment you check.
- Everyday price — the median of the last year. What it normally sells for.
- Year’s low / high — the cheapest and dearest it has been in 12 months.
- Now — the current price, measured against all of the above.
We currently read Amazon price history. We do not yet compare live prices across other retailers — so we never claim to. When multi-retailer data is added, this page will say so.
How the verdict is computed
We find where today’s price sits within its own 12-month range (its percentile) and how far it is below the everyday price:
- BUY — at or near its yearly low and clearly below everyday. Genuinely a good time.
- WAIT — it dips lower than this on a regular cycle. Hold off.
- SKIP — the “discount” is fake: today’s price is basically the everyday price, or a “was” price that never really held.
- FAIR — a normal price. Fine, nothing special.
The Deal Score (0–99)
A single number for how good the price is: how far below its usual price it sits, blended with demand. It is computed from price data only — brands cannot pay to change it.
