About these numbers. Prices are checked nightly against the official pricing page and recorded in an append-only history (data through 2026-07-07). Last hand-verified 2026-07-06. List prices only: promotions and limited-time discounts never enter the history. If a number is wrong, the correction is published, not buried: see the methodology.
