I've purchased quite a few by contacting the owner. Always specify the domian name and make your outreach email as professional and formal as possible. I never include an actual offer so I can at least get them to reply (if you offer too little, they may not even reply). I never discuss the reason for purchase. The first email is only to determine their interest and start the dialogue. If they fail to respond in a week (it takes time), I call the phone number listed on the whois record and try the personal touch.
