The primary price columns contain only current observations inside their 24-hour evidence windows, ordered from lowest to highest from the same selector used everywhere else on the site. Historical and unavailable observations remain inspectable with their source in each row and in the workbook, but cannot power a current claim. Retailer-listing records show where an exact model was found without inventing a price or stock status. Amounts are equipment-only before tax, shipping, installation, accessories, rebates, or stock guarantees. Coverage is broad but not every seller on the internet. N/A means an exact value was not published; it is never filled from a sibling model.
