How Forgotten brew(4) trades on the Grand Exchange

Potions are consumed by PvM, PvP, and skilling. Doses (1) through (4) trade at separate prices, so the same base potion can have different margins by dose. A generous buy limit here means you can fill a full cycle at once and let it sell in the background. Because it is members-only, it is only visible on the Grand Exchange for P2P accounts. Its margin has been volatile in the last hour, so treat this snapshot with extra caution and check the live numbers first.
