There was some mention of too easy to lose a paypal dispute if there are no pics or description.

So someone suggested to me once to re-list as BIN (making the buy it now price very high) with best offer and tell the buyer to put the agreed price as an offer which seller then simply accepts.

That way you don't need to expose the buyers ID in case they don't like that.

Otherwise freds idea of "This is for a private buyer only" works.
