Afternic will be even lower. Quite a bit lower. I tried them for about three weeks, and did not get near the revenue that Sedo was paying. Although, if you are mainly interested in domain sales, Afternic does a much better job then Sedo. I am still trying to finalize some domain sales that were initiated last month. Sedo has the "no minimum commission" on Sedo parked domains, but the after-sale service is just not there. I would park mine on Afternic if they would also have a no minimum commission, just for their DNEscrow service. FYI, my revenue today is running much lower then usual.
