But another reason a domain owner won't respond is because they don't think a particular buyer is legitimate enough to offer a price that they will sell for. So they start with a little friction and see what happens. Additionally if you were a big fish buyer, you would also follow a certain pattern if initially rebuffed. All this depends on the domain and the situation of course. If a large company wants your name they could start out any number of ways. But eventually they will throw a decent offer on the table to let you know they are serious. Obviously everything is for sale at the right price.
