Bones

The Bones is a free-to-play Old School RuneScape item — “Bones are for burying!”. Its Grand Exchange buy limit is 3,000 per 4 hours. Right now it buys at 33 gp and sells at 37 gp — a net margin of 4 gp (12.1% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.

To flip it, place a buy offer near 33 gp and a sell offer near 37 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
