Wrong shop information should be reported with a source whenever possible. Use the correction option from the listing or start at corrections and include the shop name, city, state, the field that is wrong, and the official page or photo that supports the update. The card shop directory depends on sourced facts because a card store can change address, hours, ownership, categories, or event support without every old citation disappearing from the web.
Be specific. “This store is bad” is not a correction; “the shop moved from Main Street to Oak Avenue and the official site shows the new address” is actionable. If a shop closed, include the closure announcement or a reliable current source rather than only a memory of a locked door. The methodology page explains why CardShopMap separates sourced directory facts from opinions. Better corrections help collectors avoid wasted trips and help real shops avoid being buried under stale data.
