No affiliate links, sponsored placements or paid rankings appear on this site. Ordering follows the sourced data and the stated criteria.

A rank whose 80% interval overlaps its neighbour's is an ordering, not a finding; the intervals are on each provider's page and in /scores.json.

When these numbers change, hear about it. Sources are re-checked monthly; a repricing goes out as a short note.
