Domain name renewal costs are less than many other leading domain registrars. Rather than offer registration either at very low prices or for free - then increase renewal charges to cover for that first time cost, we try and keep more of a level cost across domain registration and renewals.
Domain renewals don't require you to do anything. Once you've registered your domain name, we will automatically renew it, unless you set it to expire at the next renewal date. This way, you won't have any downtime of your website or emails.
With renewals, best practice is to let domain renewal run automatically to ensure continued use of your domain. If it is allowed to expire, then you run the risk of a third party registering it. If you're sure you don't need the domain any longer, then you can set it to run the normal course of expiration.
