The flip, step by step

1. Place a buy offer at or just above 45 gp (the current instant-sell price).
2. Wait for the fill. Sweetcorn is very liquid right now, so offers usually fill within minutes to a quarter hour.
3. Re-list at or just below 65 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 (11,000 per 4 hours), a full cycle is 209,000 gp on 495,000 gp of capital.
