American mumsnetters - high school graduation gifts

[Paq]

My nephew in Boston is graduating next week. What's an appropriate gift from a loving but not flush aunt?

He's off to college in September so something for that adventure might also work?

I’m sure an Amazon gift card would be much appreciated. He’ll have lots of stuff to buy for his dorm if living on campus. I don’t think there are usually any ‘traditional’ gifts other than money.

We got our two kids theirs here in the school colors, they used them for all 4 years, and now for travelling, something they didn't think of but definitely needed and loved:
