Why clean, structured price data matters

• Resale arbitrage: spot underpriced items on one marketplace to flip on another.
• Price monitoring: alert when a watched item crosses your buy/sell threshold.
• Market research & trend analysis: understand what sells and at what price.
• AI/ML training: labelled price + condition + category data for prediction models.
