Purple dye

The Purple dye is a free-to-play Old School RuneScape item — “A little bottle of purple dye.”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 262 gp and sells at 161 gp — a net margin of -104 gp (-39.7% ROI) after the 2% Grand Exchange tax of 3 gp. High alchemy yields 3 gp.

To flip it, place a buy offer near 262 gp and a sell offer near 161 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
