In order to purchase a VeeFriends NFT, you will need to conduct two important steps. First, you will need to purchase ETH from a crypto-currency exchange such as Coinbase, Gemini, or Binance. Once you have completed that step, you will need to transfer your ETH into a non-custodial digital wallet like MetaMask, Portis or WalletConnect compatible wallets. These wallets connect to the VeeFriends website and allow you to purchase an NFT. For your reference, here are blog posts outlining in detail how to set up a crypto wallet, as well as the basic steps to take to send ETH to your wallet.
