Buyer pays. Doesn't make any effort to get the domain they "bought". Wait wait wait, nothing happnes. And marketplaces don't pay us, because buyer didn't get the domain. Both Sedo and Afternic does this. In such a case the marketplace should take the domain. I'm ready to push it. Sometimes domains can't be transferred to another registrar. Then what will happen: cancel the transaction? Very annoying. Sedo and Afternic need a serious competitor.
