How Guam tar trades on the Grand Exchange
Herbs feed the potion economy. Grimy from farming and drops, clean into potion-making. Volumes are typically high and spreads tight. A very high buy limit means one full cycle can move a lot of capital, so the margin per unit does not need to be large for the flip to be worth doing. Because it is members-only, it is only visible on the Grand Exchange for P2P accounts.
