I have a good idea for a product, or line of products rather, and have an awesome and appealing name for it. I go to buy the domain name and it says it is already taken. I did the "whois" for it and emailed the admin, or the email he gave anyway. If he does reply how can I buy it from him when he owns it already? How does that transaction work? And if he does not reply, what other way can I get it??
