You are able to purchase domain names from many places. We recommend purchasing a domain from a more well-known and popular seller such as:
- GoDaddy: http://www.godaddy.com
- Google Domains: http://domains.google.com
- Hostgator: http://www.hostgator.com
If you end up purchasing your domain name from a different service, we recommend that you make sure it is a well-known and reputable company.
