Overview
Real-time price comparison badges for eBay TCG listings.
CardShark shows you the real market price of every Magic, Pokémon, and Yu-Gi-Oh! card on eBay, right next to the listing, in real time. Completely free, no account required. Scrolling through eBay search results, it's hard to tell at a glance which listings are actually good deals. CardShark fixes that: it overlays a price badge on every TCG listing showing how the seller's price compares to current market price, so you can spot underpriced cards instantly. How it works - Browse eBay search results or a listing page for Magic: The Gathering, Pokémon, or Yu-Gi-Oh! cards - CardShark reads the listing title, matches it to the correct card (accounting for misspellings, set codes, foil/holo variants, and language), and pulls the current market price from free, public price databases - A badge appears next to the price showing the market price and how it compares: - Red priced above market - Gray within 15% of market price - Green underpriced 15-20% below market - Flashing green underpriced 20%+ below market, a real deal Smart matching, not just keyword search - Detects card condition (NM, LP, MP, HP, damaged) from the listing title and adjusts the comparison price accordingly - Matches foil/non-foil, special treatments, promos, and set codes so you're comparing against the correct print — not just the cheapest version of a card's name - Fuzzy-matches misspelled or abbreviated card names - Converts non-USD listing prices to compare against USD market prices
