Price and Refund policy:
The minimum registration period is 10 years and the retail cost is US$1000 for the 10 year period. As we prefer you to use the services of a Registrar, many Registrars may offer you discounts off our retail price.
Please note included in the retail price is the "one-off" domain set up fee of US$600 and the US$400 representing the annual payment in advance for the 10 year registration period.
Should the Administrative Contact on behalf of the Registrant decide to cancel the domain registration before the end of the initial 10 year term, we will refund, all unused annual increments to the account that paid us. No other registry offers such a refunds policy.
