Purchasing luxury goods through resale platforms like OOPBuy can be exciting, but the risk of encountering counterfeit items remains a significant concern. By implementing a systematic approach using spreadsheets, buyers can minimize these risks and make informed decisions.

1. Document Every Transaction Detail

Create a spreadsheet to log all purchase details, including:

• Item name, brand, and model number
• Seller's username and ratings
• Date of purchase and price paid
• Listing photos and descriptions

This creates a reference point to verify authenticity by cross-checking with the original product specifications.

2. Track Authenticity Verification Steps

Use your spreadsheet to record each verification method used:

• Serial numbers or hologram tags
• Third-party authentication services* (e.g., Entrupy, Authenticate First)
• Comparison with official brand packaging/materials

*Note results in a dedicated column for future reference.

3. Analyze Seller Patterns

A shared spreadsheet among buyer communities can help:

• Flag sellers with repeated counterfeit complaints
• Identify suspicious pricing patterns (e.g., consistent 50% discounts)
• Share approved authenticity checklists for specific brands

4. Implement an Inspection Schedule

Create conditional formatting to highlight:

• Items needing urgent professional authentication
• Upcoming return policy deadlines
• Credit card dispute filing windows
