Rum (red)

The Rum (red) is a members-only Old School RuneScape item — “Alcohol in the loosest sense of the word.”. Its Grand Exchange buy limit is effectively unlimited. Right now it buys at 101,000 gp and sells at 144,000 gp — a net margin of 40,120 gp (39.7% ROI) after the 2% Grand Exchange tax of 2,880 gp. High alchemy yields 120 gp.

To flip it, place a buy offer near 101,000 gp and a sell offer near 144,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
