Yellow dye

The Yellow dye is a free-to-play Old School RuneScape item — “A little bottle of yellow dye.”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 233 gp and sells at 343 gp — a net margin of 104 gp (44.6% ROI) after the 2% Grand Exchange tax of 6 gp. High alchemy yields 3 gp.

To flip it, place a buy offer near 233 gp and a sell offer near 343 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
