If you cancel within 30 days and your plan includes a free domain, Bluehost will deduct a non-refundable domain fee of 15.99 from your refund. This not only covers our costs, but ensures that you won't lose your domain name. You may transfer it to another registrar or simply point it elsewhere at your convenience. Please note newly registered domains cannot be transferred to another registrar during the first 60 days of the registration period. You retain ownership of your domain until the end of its registration period unless you renew it.
FatCow has one of the cheapest offers for an entire website package, with hosting and domain names for just thirty cents during your first month. After, that the price is $10.99 a month or $59.88 for the whole year, in a shared hosting package with enough bandwidth for most people. This is a limited promotion I found, but they still sell fairly well-priced packages (their "fat" options come with extras like marketing and advertising credits), and will gladly offer you perks for transferring your domains and hosting to them.
Domain names can be used in a number of ways. Direct visitors to your website’s home page or use complementary domains to send them to specific areas of your website ( e.g. yourcompany.jobs for a careers page). Or, forward a custom domain to an existing social media account, like your Twitter profile or Periscope channel. With a domain name you can even set up custom email addresses like email@example.com, which can be used to conduct business or communicate with your followers. More.
