Been playing since Vanilla, I remember when I'd charge like a gold for a port. Or sometimes if they just covered the cost of the reagent, I'd port them. Now days, they're just throwing money at me (even when the hearth has been taken down to 30mins from what used to be 1hr). I get 10-30g usually. I never state a price, but when people open trade that seems to be the 'going' price on my server anyway.
If you add it all up, I've made a pretty damn healthy profit just from ports alone.
