I use cloudflare, and their prices are unbeatable.

"Cloudflare Registrar is only available for customers that use Cloudflare as their authoritative DNS provider (also known as a full setup)."

Wow. Just wow. What happens if I register a domain via Cloudflare but decide later I don't want to use their DNS offerings?

You transfer it, hoping that they don't refuse and decide they own you forever.

You can transfer the domain to some other registrar.
