How to flip Weeds in OSRS

Flipping Weeds on the Old School RuneScape Grand Exchange currently makes about 30 gp profit per item after the 2% GE tax: buy near 100 gp (the instant-sell price) and re-list near 132 gp (the instant-buy price).

• Buy at (instant-sell): 100 gp
• Sell at (instant-buy): 132 gp
• Margin after 2% tax: 30 gp (30.00% ROI)
• Buy limit per 4 hours: 600
• 24h volume: 77,204 (very liquid)
• Max profit per limit cycle: 18,000 gp on 60,000 gp of capital

The flip, step by step

1. Place a buy offer at or just above 100 gp (the current instant-sell price).
2. Wait for the fill. Weeds is very liquid right now, so offers usually fill within minutes to a quarter hour.
3. Re-list at or just below 132 gp (the current instant-buy price).
4. The GE takes 2 gp tax (2%) per item when it sells, leaving 30 gp profit each.
5. Repeat up to the buy limit (600 per 4 hours), a full cycle is 18,000 gp on 60,000 gp of capital.
