Various tools are available to sell all card games on CardShark. These include a basic listing ability - when you search for a card you will see a "Sell Your Copy" button that allows you to list your cards one at a time.
You can also use the basic inventory management tool listed on your "My Account" page under "Manage Inventory".
In addition to these standard tools, we have a
CSV Import
Program that will let you upload all of your Magic Online inventory nightly.
Please view the program notes for more information on how to use this advanced tool.
