My suggestion would be to put in place a global search option in the game. Players could now post up to three items or so and place them in the search posts.
Other players could then see the post from any town and automatically warp to the current location of the seller as long as they are in an available town. Now, wouldn't that be a nicer way to jump from one campaign to another as well?
Just thought it might make the whole trading aspect of the game much less time consuming and less remote.
