You can purchase NFTs if you see a Buy now option. Only NFTs with this option are available for direct and immediate purchase.
If the Buy now option doesn’t exist on the NFT Detail page, then the NFT isn’t for sale.
Fees
The fees to purchase an NFT at a fixed price (non-auction), is the price of the NFT plus the gas fee. When you select Buy now, you'll see the gas fees for the time of purchase.
Are NFT purchases reversible?
No, any transactions made on the blockchain, including NFT purchases, are irreversible due to the nature of the blockchain.
You can however, opt to resell your purchased NFTs at a fixed price on Coinbase NFT, or resell it in an auction elsewhere. Please be aware that any royalties to the Creator, and transaction fees may also incur with each sale.
