Purple hat

The Purple hat is a members-only Old School RuneScape item — “A silly pointed hat.”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 1,262 gp and sells at 2,300 gp — a net margin of 992 gp (78.6% ROI) after the 2% Grand Exchange tax of 46 gp. High alchemy yields 300 gp.

To flip it, place a buy offer near 1,262 gp and a sell offer near 2,300 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
