I was going through some old email messages yesterday when I came across a conversation from two-and-a-half years ago:
Me: "Is [domain] for sale? I have a client who may be interested in purchasing the domain at the right price."
(I was attempting to purchase the domain for my own use.)
Other person: "Not really. Had some ideas to develop the domain. I am always willing to consider a good offer though."
Me: "Thanks, ____. My client has authorized me to offer $300. Let me know."
