General Best Practices, Risks, and Pro Tips​

For Buyers:

1. Research thoroughly: Use completed listings (eBay), comparables on WorthPoint, Google, or specialist sites. Check condition reports.
2. Set a strict budget including buyer’s premium (10–25%), shipping, taxes, duties, and insurance.
3. Use proxy/max bidding to avoid emotional overbidding and sniping.
4. Verify seller ratings, authenticity (especially for high-value items — request expert opinions).
5. Read all terms: Returns, warranties, payment deadlines.

For Sellers:

1. High-quality visuals: 10–20+ photos from multiple angles, videos, detailed descriptions with keywords, measurements, provenance, and condition.
2. Competitive pricing: Realistic starting bids, strategic reserves.
3. Timing: Align with peak seasons or related events.

Advanced Advice: Use tools like Terapeak (eBay), auction analytics apps. For international: Services like Shipito, DHL, or platform-managed shipping. Track taxes via accountants. Monitor communities (Reddit r/Flipping, r/eBaySellerAdvice). Start small to learn.
