Understanding COMC Fees & Consignment

COMC (Check Out My Cards) is a consignment marketplace for sports cards, trading cards, and gaming cards. Unlike selling on eBay where you handle everything, COMC processes, stores, photographs, and ships your cards for you. Understanding their fee structure is key to profitability.

  • Monitor Storage: Withdraw or reduce prices on slow-moving inventory
