All extra domains share the disk space allocated to the original account. Note that this amount does not include domain registration. If you do not yet own the domain that you would like added to your account, you will still have to pay the annual fee to register it. If you would like a secure server, but aren't interested in the Strictly Business plan, then you may add this service to any other plan. Check out our FAQ for more information.
Bulk discounts are available, so feel free to contact our sales department.
