Sellers ranked. By what matters.
The ranking algorithm reads your collection in real time. Seller #1 has the most of what you actually need — not the most cards overall.

Sellers ranked by your missing cards
The seller with the most of your missing cards sits at #1. No other marketplace does this. The ranking updates live from your collection.
Browse any seller like a mini-collection
Tap a seller to see their full inventory organised by series and set — the same view as your own collection. Instantly see what matches your gaps.
Multi-seller checkout
Add cards from multiple sellers in one session. Orders are grouped by seller at checkout — one payment flow, multiple sellers.
Zero buyer fees
You pay the listed price plus delivery. That's it. No platform fee, no processing charge, no surprise at checkout.
Per-order fee structure
Carder charges the seller once per order — not once per card. Buy 50 cards from one seller and the fee is applied once. Cardmarket charges per transaction.
