I want to sell this domain, allmyhosting.com, I sell it for 15 $, the domain is on dotregistrar, so free push possible on dotregistrar, or you can transfert it away, but the transfert price is your cost.

What does dotregister charge to transfer to other registrars?

The price for trasfert away, depend from the new hoster, so you must see offers on your favourite registrar.
