The real price of your exact copy on Cardmarket card pages: same language, condition and foil. Not affiliated with Cardmarket. Comps shows the real price of the copy you're selling or buying on every Cardmarket card page. Cardmarket's "From" price and price trend mix every language and condition, so a Japanese Excellent copy can set the "From" price for your English Near Mint card. Comps reads the offers on the page and keeps only the ones that match your copy: same language, same condition or better, same foil, reverse holo or edition. You see the cheapest of those, the median of the five cheapest, how many there are, and a suggested price you can copy into your listing with one click. What you get for free: • A price panel above the offers on every singles page, for every game Cardmarket sells. • Language, condition, foil, reverse holo (Pokémon) and edition (Pokémon, Yu-Gi-Oh!) filters, remembered per game. • A warning when Cardmarket's "From" price belongs to a different copy, and by how much. • One-click copy of the suggested price. • One click to show Cardmarket's own list filtered to your copy (language, condition, foil and edition), even when those offers are further down than the first page. • Your own offers never set your price: Comps recognises you when you're signed in to Cardmarket. • Works in Cardmarket's English, German, French, Italian and Spanish interfaces, and Comps itself speaks all five. Comps Pro (paid, through Polar): • Your own pricing rule: start from the cheapest offer, the median of the five cheapest or a tracker price, go under or over by an amount or a percentage, round down to .x9 or .x5, and set a minimum price for all games or per game. • Compare only with private sellers, professional sellers or powersellers. • Presets for the copies you list most, switched with Alt+1 to Alt+9. • Your own offers checked: each is marked in Cardmarket's list, with how far it sits above or below the cheapest other offer for the same copy. Polar (polar.sh) sells Pro as reseller and merchant of record. It renews monthly or yearly until you cancel it in Polar's customer portal, and refunds follow Polar's buyer terms. How to use it: Open any card page on Cardmarket, in English, German, French, Italian or Spanish. Set the copy you have in the panel: language, condition and foil. Copy the suggested price into your listing. Privacy: Comps works entirely in your browser. It reads only the Cardmarket page you have open, never submits anything for you and has no account, analytics or tracking. The only request it makes is to Polar, the payment provider, to check a Pro license key you entered. Comps is not affiliated with or endorsed by Cardmarket or by the makers of the games it supports. Cardmarket, Pokémon and Yu-Gi-Oh! are trademarks of their owners. Support: support@zeusstudio.dev
