What you charge for domains would never cover a chargeback fee.
but if you have enough security systems in place then a fraudster would not get to the point of completing any order in the first place.
I don't intend to cover chargeback fees from a single domain, chargback/refunds related to domains are usually less then 1% and again we do get payments refunded for most of the TLD if we cancel them within 2-3 days, so considering all these factors it does covers the cost for us.
We don't intend to make money by selling domains, we just sell domains so that hosting customers can get everything they need from one place.
