RareFinds Flowfor businesses that sell collectible cards
Your whole card shop. One system.
0 SEK / monthYou keep your own accountsOnline, in store and at fairs
RareFinds Flow brings buying, inventory, sales and shipping together for anyone who sells collectible cards. Scan your cards and list them on Tradera and in your web shop from the same inventory. When a card sells, the inventory updates and the listing comes down everywhere else. Less double work, more time to sell.
Only selling on Tradera, or only online? Flow works just as well. You don’t need a physical store.

01
We negotiate together
With many shops in one system, we buy shipping and payments in large volumes. That pushes suppliers’ prices down, and every shop gets those prices.
02
Partners pay us
We are paid by our partners, not by the shops. That is why the system can stay free for you.
03
You only pay when something happens
1.85% to Kustom when you sell in the checkout, and from 45 SEK + VAT per parcel when you ship with DHL. No fixed costs.
