I need to get my friend a nice and thoughtful gift, without breaking the bank. She's 15?

She wants a giftcard which I will get her, but i want to get her small other things, for like a basket.
--------------------
Does she have any interests/hobbies? Get something to fuel those. For example, my friend has loved photography for the five years that I've known her, so this year, I bought some matted picture frames on sale, and some inexpensive things to decorate them with -- I bought some pretty ribbon and hot glued it around the mat, then threaded it through some pendants I found at the craft store, hiding the ends underneath the pendant so it looked like a complete loop, and glued the pendant down in the corner. I threw in some dark chocolate Kisses (I know she can't resist them) among the tissue paper, and the whole project cost under $20. Also, most girls will love a cute "spa" basket. You can get sample-sized bath products from Bath and Body Works (Or anywhere, for that matter.) The dollar store has fun poufs and such. You could even throw in an inexpensive mug (also found for just a dollar) with a packet of hot cocoa and a candy cane (to stir with minty goodness for a treat to enjoy while she relaxes) and once again, you can achieve this for $10 or less.
