Gold locks

The Gold locks is a members-only Old School RuneScape item — “Perhaps someone can do something with this.”. Its Grand Exchange buy limit is 8 per 4 hours. Right now it buys at 18,420 gp and sells at 18,999 gp — a net margin of 200 gp (1.1% ROI) after the 2% Grand Exchange tax of 379 gp. High alchemy yields 19,200 gp.

To flip it, place a buy offer near 18,420 gp and a sell offer near 18,999 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
