If you bought your full buy limit on Marrentill potion (unf) right now, you'd clear roughly 270.0K GP after the 2% GE tax. That's the ceiling. The actual margin shifts every few minutes, especially after Wednesday updates and weekend supply spikes.

How Marrentill potion (unf) 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.
