Godaddy is one of the largest web hosts in the US. They are one of the few companies in the web hosting industry to use television as an advertising medium. Even if you plan on hosting your site elsewhere, GoDaddy is a safe option for domain registration services. Be sure to keep an eye out for their auto-renewing domain services as well.

You can sign up for services or register a domain at GoDaddy's Website.

You can cancel most services through your online account by logging in at Godaddy.com. For a more complete step-by-step guide to cancelling, please see: http://www.givegoodweb.com/post/56/cancel-godaddy
