How to flip the Plank
The Plank is a free-to-play Old School RuneScape item — “A plank of wood!”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 143 gp and sells at 153 gp — a net margin of 7 gp (4.9% ROI) after the 2% Grand Exchange tax of 3 gp. High alchemy yields 1 gp.
To flip it, place a buy offer near 143 gp and a sell offer near 153 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
