How to flip Banana tree seed in OSRS

Flipping Banana tree seed on the Old School RuneScape Grand Exchange currently makes about 19 gp profit per item after the 2% GE tax: buy near 50 gp (the instant-sell price) and re-list near 70 gp (the instant-buy price).

• Buy at (instant-sell): 50 gp
• Sell at (instant-buy): 70 gp
• Margin after 2% tax: 19 gp (38.00% ROI)
• Buy limit per 4 hours: 200
• 24h volume: 14,232 (very liquid)
• Max profit per limit cycle: 3,800 gp on 10,000 gp of capital

The flip, step by step

1. Place a buy offer at or just above 50 gp (the current instant-sell price).
2. Wait for the fill. Banana tree seed is very liquid right now, so offers usually fill within minutes to a quarter hour.
3. Re-list at or just below 70 gp (the current instant-buy price).
4. The GE takes 1 gp tax (2%) per item when it sells, leaving 19 gp profit each.
5. Repeat up to the buy limit (200 per 4 hours), a full cycle is 3,800 gp on 10,000 gp of capital.
