How to flip Whiteberry seed in OSRS

Flipping Whiteberry seed on the Old School RuneScape Grand Exchange currently makes about 1 gp profit per item after the 2% GE tax: buy near 5 gp (the instant-sell price) and re-list near 6 gp (the instant-buy price).

• Buy at (instant-sell): 5 gp
• Sell at (instant-buy): 6 gp
• Margin after 2% tax: 1 gp (20.00% ROI)
• Buy limit per 4 hours: 200
• 24h volume: 25,607 (very liquid)
• Max profit per limit cycle: 200 gp on 1,000 gp of capital

The flip, step by step

1. Place a buy offer at or just above 5 gp (the current instant-sell price).
2. Wait for the fill. Whiteberry seed is very liquid right now, so offers usually fill within minutes to a quarter hour.
3. Re-list at or just below 6 gp (the current instant-buy price).
4. The GE takes 0 gp tax (2%) per item when it sells, leaving 1 gp profit each.
5. Repeat up to the buy limit (200 per 4 hours), a full cycle is 200 gp on 1,000 gp of capital.
