That's a common step into more advanced DeFi. You're right to want a direct purchase to avoid extra steps and fees. Look for a service that offers a straightforward fiat-to-LINK gateway. For instance, you can use paybis.com/buy-chainlink/. It lets you specify the amount of LINK you want, shows you the exact cost with fees included, and you can pay with a card or transfer. The tokens get sent directly to your wallet address. It's much simpler than dealing with trading pairs on a spot exchange for a one-time purchase.
