How to flip the Oyster
The Oyster is a members-only Old School RuneScape item — “Maybe there are pearls inside?”. Its Grand Exchange buy limit is 11,000 per 4 hours. Right now it buys at 20 gp and sells at 22 gp — a net margin of 2 gp (10.0% ROI) after the 2% Grand Exchange tax. High alchemy yields 120 gp.
To flip it, place a buy offer near 20 gp and a sell offer near 22 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
