The experience bottle trader was a secret, and only those who actually explored the map's roads and little roadside builds would find it. There were a few secrets out in the world like that. As far as I recall, only Naelwyn knew that the trader existed besides myself, because he was selling the potions at a 50% markup in Rota Magna (where everyone bought them, not knowing where else they could come from).
On the same map was a secret trader in the Port Silver lighthouse near the prison. He'd trade 9 diamond blocks and 3 wither skulls for a nether star. Besides the very few Withers that have been deployed in events, that merchant is the source of every nether star on the server, four years on.
