Have you considered sending them a physical letter? You can put a lot of digital goods as codes there (even steam games, albeit bought in 3rd party stores), also gift cards like ‘$10 in X store chain’ if that’s a thing at their place, but the novelty (hehe) of getting a birthday card that they can keep is waaay more cool than a gift notification. See if that’s possible and is up your alley.
Let’s keep it this way.
