Amazon gift card from their UK site.
My parents in France bought me a gift card from the Amazon US site for my birthday. It worked great!
You're a thoughtful Godparent, OP, but I urge you to continue giving small presents for the next few years. 18 year olds are rarely physically or psychological independent. My Godmother stopped slipping me bills when I got married! And now she gives French chocolates to my kids whenever I bring them to Paris. The Godparent thing, like the parent thing, never really stops...
