How to flip the King worm
The King worm is a members-only Old School RuneScape item — “They're a gnome delicacy apparently.”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 438 gp and sells at 509 gp — a net margin of 61 gp (13.9% ROI) after the 2% Grand Exchange tax of 10 gp. High alchemy yields 1 gp.
To flip it, place a buy offer near 438 gp and a sell offer near 509 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
