This sucks, and seems to be pretty stupid to me. And it could hurt not only the Seller but also Sedo. As far as I read this, the only way to sell a domain with a minimum $50 commission is to park it at Sedo and have a fixed price, with the latter being the new addon rule. So let's say you have a 'eh' domain. You want to sell it, and don't think you could get more then $200. So you list it for $200, and if it sells, Sedo takes $20. But let's say you had Make Offer, and you negotiated to $1000. Not only did the seller theoretically lose $800 in sale price, but Sedo lost $80 in commission.
