Card Edge is a real-time card arbitrage Discord built for serious collectors, flippers, and investors. We continuously monitor eBay to identify listings priced below the most recent sold comps and deliver alerts to Discord the moment a deal appears, giving you the chance to act before the market corrects.

This is not a price guide and it does not rely on 30-, 60-, or 90-day averages. Every alert is based on fresh sales data and live listings, ensuring pricing is anchored to what the market is actually paying right now.

Cards are manually added to the system, starting with the most liquid and highest-volume markets to keep signals clean and actionable. Recently sold listings are scanned to determine the most recent completed sale, and active listings are compared directly against that price. When a listing is meaningfully under market, an alert is sent instantly with a direct link to the listing.

Coverage focuses on high-volume sports and Pokémon cards, with ads, sponsored listings, and promotional results filtered out. New card requests are always open, and a full list of currently tracked cards is available inside the Discord.

Card Edge is built for sports card flippers, Pokémon collectors, arbitrage-focused buyers, and anyone looking for an edge in fast-moving markets. Alerts are last-sold based, not average-based, and while deals are not guaranteed profits, speed matters — underpriced listings do not last long.
