Yeah I wouldn't worry too much about the markets either, if you're willing to spend a couple minutes searching across the kingdom lists you can very easily just export your goods to a high priced kingdom and reap the rewards. For example I produce the finest of Wine, which on average sells at around 6 and 80 a barrel in most markets but you can find places where it will go for 9 gold a piece!
@Richyy the game is real slow paced and unfortunately the King of Milan is very hesitant to launch battles or take any diplomatic actions that might cause anything interesting to happen, however I'm regularly launching crusades and trying to galvanise him into action whenever possible.
