Both of the txs referenced in the writeup have tx fees so I'm just making sure I'm seeing it right :) There's a pretty real possibility of btc tx fees going up if the volume grows and block size stays the same especially once mining fees get halved so if as a seller I have to pay tx fees that is something the protocol description should mention.
