There are quite a few places to register your domain. I use Fabulous and Domainsite as my primary domain registrars. They are reliable and have good security which is a must these days. Anything over $10 a year per domain and your probably paying too much.

That, of course, doesn’t include hosting a website of any kind. I use Hostgator for my site hosting. They run about $60 a year for “unlimited” sites meaning you can host 2, 3, 10, or 30 sites with them all for $60.

You can have your domain and website hosted at different places.
