• Instant market comparison: Compare against recent sales & market values.
• Automated alerts: Get notified of underpriced listings before competitors.
• One-click purchasing: Eliminate checkout delays.
Winning Strategies for Beginners:
- • Start with lower-risk purchases: Focus on ungraded trending player cards before moving into high-value graded cards.
• Use sniping tools: Set alerts for PSA 10 rookie cards at 20% below market.
• Target sellers with low feedback: New sellers often misprice valuable cards.
• Understand auction vs. BIN: Auctions typically close 5-10% lower, but BIN offers speed.

✅ Entrepreneurs looking to source inventory at 20-40% below wholesale.
✅ Serious collectors with deep market knowledge.
