Shortlist in phone lookups
Ranking rule: Lowest per-1,000 price in US dollars first, at the best volume tier the page prints. Where a page prints only a price per request, the per-1,000 figure is our arithmetic and is shown as "about". Providers with no dollar per-1,000 figure we can compare come after, and ties go by name.
