How this record is made

A scheduled worker reads the public Apple Certified Refurbished category pages twice a day and keeps the product name, configuration string, SKU and price of each listing. Nothing else is collected: no cookies, no analytics, no accounts, no affiliate tags.

What is measured, what is inferred

Measured: the listing exists on that date, at that price, with that configuration. Inferred: the category grouping, derived from the product name, and the cheapest and median figures, which are arithmetic over the measured rows.

What this cannot tell you

A listing price is not a value judgement. No discount percentage is computed, because that would require the new price of the identical configuration, which Apple publishes on a different page that changes independently.

A price is the one read at that moment. It may already be stale by the time you click through.
