I mistyped the domain name when registering. Can you issue a refund?

According to the Registration Agreement, domain name registrations or renewals are non-refundable.

If you want to get rid of your domain, you can try to list the domain name for sale at our Marketplace and set your own price (within the limits of $5 to $1000) for it.
For this, please refer to How do I list domain for sale.
