About this extension
Cardmarket Companion is an unofficial Chrome extension for Cardmarket
sellers and buyers. It prefills your listing prices from live trend data, keeps you competitive against pro sellers, and turns order pages into a pick-and-pack checklist. Works with every game on Cardmarket: Magic The Gathering, Pokémon, Yu-Gi-Oh!, One Piece, Lorcana, Flesh and Blood and the rest.
No more typing prices card by card.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
💰 PRICE FASTER
• One-click price prefill from trend (1, 7 or 30 days), lowest price or average price
• Pro Mode: auto-undercut the first professional or power seller by a fixed amount or a percentage
• Price offsets per mode, plus a minimum price floor so nothing is ever listed too cheap
• Preview panel before you list: card, condition, price and price source
📦 PACK ORDERS WITHOUT MISTAKES
• Tick off each line as you pick it; a counter shows what is left, saved per order so an interrupted pack resumes
• Quantities colour-coded (2-4 amber, 5+ red) so you never ship one card when two were sold
• Group an order by expansion to match how your stock is filed
• Cards below Near Mint or in an odd language are flagged for a second look
🛒 BUY SMARTER
• Estimated shipping cost shown on listing pages, no need to fill a basket to find the real total
• Card images instead of tiny camera icons on Offers, Products, Wants, Shopping Wizard and Orders
⚡ WORK YOUR WAY
• Reusable comment presets and a default message signature
• Live tracker: cards listed and total value as you go
• Copy and export your card list to share with friends or teammates
• Toggle card images per page, hide social buttons, keep the layout you want
🔒 PRIVACY
Your pricing data stays in your browser. Nothing about your business is
sold or shared.
