You can either use an existing domain you purchased from another registrar, or purchase a new domain name when you setup web hosting with TurnKey Internet. New domain registrations require a registration fee as shown during the sign up process. There is no cost to use an existing domain name, unless you wish to transfer it to TurnKey Internet. The fee to transfer a domain to TurnKey Internet's registrar includes a 1 year renewal in addition of any time left on the domain name's registration period.

You do not need to transfer your domain to TurnKey Internet to use an existing domain, instead you can use the current domain name(s) you already own simply by pointing the DNS (domain name service) for those domain name(s) to your new web hosting account. Full details on this will be emailed to you once you sign up.
