1. Research & Niche Selection

Start by identifying a niche you enjoy—whether it’s action figures, vintage watches, or sports cards. Use tools like Google Trends, Reddit communities, and eBay’s sold listings to gauge demand and price points.

Find inventory at thrift stores, estate sales, garage sales, and online liquidation sites. Building relationships with local collectors or attending conventions can also yield hidden gems.

5. Optimize Listings

High‑quality photos, keyword‑rich titles, and detailed descriptions boost visibility. Use SEO‑friendly terms like “2026 rare”, “mint condition”, and “collectible”. Include a short video if possible—buyers love seeing items in motion.

Prompt communication and secure packaging are crucial. Offer multiple shipping options and consider insurance for high‑value pieces. Automate label printing with services like ShipStation to save time.
