I sold a site in the marketplace and have not heard from the buyer for over 1 week, despite my attempt to try and contact him via email (I don't have a phone number for him). Immediately after the sale, we were communicating back and forth, but for the past week or so he seemed to have fallen off the face of the earth. Since the sales are legally binding, at what point can I move on and keep the site if I can't get a response from the buyer? No contracts were yet signed and no money was transferred.
I'd like to keep it too, so I don't mind the cancellation.
