How to flip the Swamp paste
The Swamp paste is a members-only Old School RuneScape item — “A tar-like substance mixed with flour and warmed.”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 19 gp and sells at 20 gp — a net margin of 1 gp (5.3% ROI) after the 2% Grand Exchange tax. High alchemy yields 18 gp.
To flip it, place a buy offer near 19 gp and a sell offer near 20 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
