Selling an NFT will incur 1 or 2 costs:
1. The Marketplace Fee - The fee that is charged by GameStop.
2. The Creator Royalty - The fee charged by the creator of the NFT, and is earned by them. This is optional for the creator of the NFT to set, therefore it could be 0, or up to 10%.
Listing an NFT for sale incurs no fees; fees are only charged upon a successful sale.
