How we turn a year of prices into a BUY / WAIT / SKIP / FAIR verdict
Every verdict comes from a product’s real selling history — not an invented “was” — and the math is simple enough to check yourself.
Where the data comes from
We read a product’s daily price research for the past year from independent market-price research that 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 a year.
- Now — the current price, measured against all of the above.
We currently read Amazon price research. 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.
AI-driven methods
Some optional helpers on the site are AI-driven — for example turning a natural-language search into filters, or summarizing on-page product details when you ask. Those helpers never invent a price or a BUY / WAIT / SKIP / FAIR verdict. The verdict itself always comes from recorded prices and the rules on this page. See our privacy policy for what leaves the site when you use those helpers.
How the verdict is computed
We find where today’s price sits within its own year-long 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.
