The most profitable trade run I ever came across was from either omega 3 or omega 7 (Iforget which), where diamonds are dirt cheap, and selling them on planet leeds. Hope this helps. Oh, the omegas are inbetween bretonia and rheinland, you can get to them from cambridge or Stuttgart.

The Most Profitable is supposedly Cardamine from Yanagai Depot to Planet New Berlin, don't know what's going back, but that's easily figured out from that point on. Of course it's considered "smuggling" and if the police catch you near the Planet you can't land, but you can make over probably 2 mil. an hour doing that run...some people say in SP the Jump Hole's still there and you can get over 4 mil. and hour, haven't confirmed it myself.

Buy 4 litres of milk at 7-11 and sell to Mac's for 4 cents profit. Works everytime.

Sometimes you're the Windshield...Sometimes you're the Bug...

i did the yanagi to berlin run. made it twice and from then after scanned by the police or mulitary about every 30 seconds. But since im in a humpback running for the omegas now...LOL

The New Berlin -> Yanagi Depot (using jumpholes) run can be made in 4 minutes(with practice) round trip. Cardamine to New Berlin and engine components to Yanagi. You'll ring up over 4 million/hr. In a Dromedary. Another good run is from New London -> Cadiz Base in Omega 5. Take engine components to Cadiz and artifacts to New Berlin. Round trip of 11 minutes. This is probably the second most profitable in the game.
