Before you can buy a pre-owned domain name, you will need to find out who the owner is. You can obtain details about the owner of a domain name by checking the Who-is information about the domain. To do this, simply visit a reputable domain registrar such as Widest.com and look for a “Whois” link.
Not all domain owners would be willing to sell their domains. These domain owners may understand the real value of their virtual real estate and may decide to keep them for future development or until domains appreciate in value.
Domain names that are listed on aftermarket sales websites such as eBusinessDomains.com are generally for sale. These websites will give specific instructions regarding how you can either buy or make an offer for the domain name.
The easiest way to see if a domain name is for sale is to type the domain name into your browser window and check the landing page. If the owner wishes to sell the domain name, there will normally be a message on the landing page that indicates that the domain name is for sale. Normally there would be a link by which you could contact the seller directly, either by email or by completing an online form with your details.
If a price is listed with the domain, then normally that is the Buy-it-now price, and is often not negotiable. If there is no price, then the buyer and seller will have to negotiate until they can agree on a price to make a deal.
