Guthix balance(3)

The Guthix balance(3) is a members-only Old School RuneScape item — “A potion of harralander, red spiders eggs, garlic and silver dust.”. Its Grand Exchange buy limit is 2,000 per 4 hours. Right now it buys at 257 gp and sells at 266 gp — a net margin of 4 gp (1.6% ROI) after the 2% Grand Exchange tax of 5 gp. High alchemy yields 120 gp.

To flip it, place a buy offer near 257 gp and a sell offer near 266 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
