Selling by DM is a mess. An open board isn't.
“Is this still available?”
One link answers everyone.
“Would you take $50?”
Not when everyone can see the top bid.
…and then silence
Everyone hears back. Won or not.
What they see
Send the link. This is the other end.
A number, a name, done. Everyone sees what to beat.
