>But your domain name registrar? Pick them carefully, don’t skimp,

Especially because domain names are not expensive anyways, a dot com (gold standard of domains) has a cost to registrars of like 11 USD right now, so registrars can charge anywhere between 15 USD and 25 USD, maybe you can find one selling at cost at 11USD or at a loss with promotions even!

But we are talking about saving 10$/year? That's less than 1$/mo. Trying to save 1$/mo is strictly in the terrain of underfunding your business, if you can't allocate enough funds so that Domain costs become a non-issue (and a provider like namecheap stops being attractive) then you will fail in a thousand ways, it's not just about domains at this point.
