Blighted vengeance sack

The Blighted vengeance sack is a members-only Old School RuneScape item — “Enough power for a Vengeance, blighted so it can be used only in the Wilderness.”. Its Grand Exchange buy limit is 10,000 per 4 hours. Right now it buys at 67 gp and sells at 67 gp — a net margin of -1 gp (-1.5% ROI) after the 2% Grand Exchange tax of 1 gp. High alchemy yields 18 gp.

To flip it, place a buy offer near 67 gp and a sell offer near 67 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
