Hi, @annakassai. The short answer is “yes”.
After you register the domain, just click the button that says “Disable auto-renewal”. If you do that, the domain will begin the expiration process once the year is up and you won’t be billed for it again.
One that thing I want to mention - you can register domains anywhere and use them with Netlify. Registering the domain with us isn’t mandatory. Using any third-party registrar will also work and then you can connect the domain to the Netlify site using one of the two method below:
If you register the domain using Netlify, then the second option above (Netlify DNS) is automatically enabled.
If there are other questions, we’ll be happy to answer.
