How to flip the Blue crab
The Blue crab is a members-only Old School RuneScape item — “You'll need something to break through that shell.”. Its Grand Exchange buy limit is effectively unlimited. Right now it buys at 356 gp and sells at 911 gp — a net margin of 537 gp (150.8% ROI) after the 2% Grand Exchange tax of 18 gp. High alchemy yields 75 gp.
To flip it, place a buy offer near 356 gp and a sell offer near 911 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
