I think we all know how difficult teenagers can be to please. The real trick is finding out what they love (say music) and chose a not-so-obvious item (great headphones - instead of an itunes gift card). A lot of teenagers like to stand out, and color is a great way to do that. Ever notice how teens often wear bright and mis-matched colors? I rest my case. In summation, think colorful, quirky and not a gift card.
