Purple cape

The Purple cape is a free-to-play Old School RuneScape item — “A thick purple cape.”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 300 gp and sells at 500 gp — a net margin of 190 gp (63.3% ROI) after the 2% Grand Exchange tax of 10 gp. High alchemy yields 19 gp.

To flip it, place a buy offer near 300 gp and a sell offer near 500 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
