DATA ACCURACY
What we know. What we don’t.
Understand freshness, identity uncertainty, unknown shipping and gaps in GPU price observations before using a comparison.
Read the observed time
An offer timestamp is when we last observed the listing—not a guarantee that the price is live at this instant. Current listings must pass freshness and eligibility checks, but changes can still happen before the next collection. All observation dates and times are shown in UTC.
If the database cannot be reached, the site retains useful explanatory content and labels price data unavailable. It does not reuse sample prices or label an unverified service healthy.
Missing means missing
Unknown shipping is not treated as zero. A missing observation is not an unchanged price. Limited history is not full product-lifetime history. No qualifying deals means the evidence did not produce a qualifying result, not that every GPU is overpriced.
Charts connect actual daily observations for readability. They do not estimate a price on unobserved days. Item-only and known-shipping price bases are shown separately, and the exact tracking start is visible.
Matching and source limitations
Merchant descriptions can be incomplete or inconsistent. We use exact product evidence where available and exclude uncertain or suspicious matches from public comparisons. Different board variants and conditions must not be silently substituted for each other.
Only approved programs and eligible sources contribute current offers. This is not coverage of every retailer. A merchant’s suggested retail price or sale label is not proof of savings against our recorded observations.
Report a problem with evidence
If a comparison looks wrong, keep the product-page address, merchant name, observed timestamp and a description of the mismatch. Never include passwords, payment details or private order information in a report.
Use the configured Contact channel when available. Until the operator has configured one, the Contact page will explicitly say that reporting is not yet available. The merchant remains responsible for its product listing and your order.
