Hes right, you might even get it cheaper that way . Thats how I sold one of mine, a guy called I spoke to him, even though I barely could hear him, which made it so I wanted to get off the phone even faster. So he thru out a number (which was very reasonable, but still not as much as I had listed it for) and told him ok. Later that night cash in my PayPal. Good way to shock and awe is a phone call.
I have bought 4+ domains this way - granted I've spent a few £k but I am happy with the domains. I have always just emailed them and I receive quite a high response back! Just go for it!
