Birthday Party Suggestions--teenagers

What does a teenager boy get for 2 teenager girls that are "just friends" of his?

Kid suggesting money.

I believe we did that twice last year, IIRC.

some nice lace underthings maybe?

just kidding, we get our kids friends gift cards to starbucks, jamba juice, cold stone, target or walmart (great places for cheap movies and music) or for the local movie theater.
