Jar of Dirt

The Jar of Dirt is a members-only Old School RuneScape item — “It's just a jar of dirt.”. Its Grand Exchange buy limit is 4 per 4 hours. Right now it buys at 41,200 gp and sells at 42,000 gp — a net margin of -40 gp (-0.1% ROI) after the 2% Grand Exchange tax of 840 gp. High alchemy yields 1 gp.

To flip it, place a buy offer near 41,200 gp and a sell offer near 42,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
