How to flip the Swamp tar
The Swamp tar is a members-only Old School RuneScape item — “A foul smelling thick tar-like substance.”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 3 gp and sells at 4 gp — a net margin of 1 gp (33.3% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.
To flip it, place a buy offer near 3 gp and a sell offer near 4 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
