How to flip the Guam seed
The Guam seed is a members-only Old School RuneScape item — “A guam seed - plant in a herb patch.”. Its Grand Exchange buy limit is 600 per 4 hours. Right now it buys at 15 gp and sells at 23 gp — a net margin of 8 gp (53.3% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.
To flip it, place a buy offer near 15 gp and a sell offer near 23 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
