Methodology.

1. Prices come from each vendor's own pricing page.
2. No public price means we show 'Price on request'. We never estimate.
3. When a review site disagrees with the vendor, we show the vendor figure and add a note.
4. USD unless stated. Tax, setup and overage can add to it.
5. Listings are re-checked at least monthly.
