> We currently, and historically, have sold .com, .net, .org domains at cost. That means at the cost we pay the registry + fees we need to cover, such as regulatory taxes and card processing fees, without any profit for ourselves.
> When we mark up other, standard domains, typically the most we do so is $1 + those fees. We often do less than $1.

Cloudflare is the least expensive registar, but they don't handle new domain registrations (only transfers and renewals), and they offer fewer TLDs than Porkbun. A combination of Cloudflare and Porkbun is the most cost-effective way to register domains in the long run, unless you're willing to deal with registrars that steeply discount only the first year.
For DNS, I use Cloudflare for everything.
However they must have different versions and detect your country based on IP address.
I like the wide range of TLDs they have.
