The cost of purchasing an NFT depends on 2 factors:
1. Listed Price - This is the price of the NFT, specified & collected by the seller.
2. Network Fee - Also known as "gas fee" - this fee is paid to the Ethereum Blockchain (or Layer 2).
When you confirm the payment, and approve the transaction in your wallet, the ETH will be deducted from your account balance.
