SG1:
Market has the option not only to issue items in specific price waiting for a buyer. It also has the option to purchase the product at a certain price. But also enjoin sell a specified quantity of the given product. Ie max 10p. It follows that a person which is not a trucker is unable to me that sell goods. And we know that starting the game is only one ship that can take up to 8-in-1 slot. And like collects on the ship to reach the max 8 plate that blocks a place on the ship, and thus has a smaller mining of asteroids. So it would be good if he could sell immediately 2-3 plate to another player and not wait a few hours for the purchase by another player, which need a plate. Of course, this method could also acquire points of trade.
I noticed that during the repair of another player using 3x hel200 at the same time include only one point to the skill.
