Some people think teens are tough to shop for, but I completely disagree. You know why? Because teens love STUFF. Any stuff, all stuff, lots and lots of stuff. Of course, it has to be cool stuff. Unless you want to be forever known as the lamest gift-giver ever. Yeah, and then my mom gave me socks. Socks for Christmas!! FAIL.

So just in case you're not sure which stuff is cool stuff and which stuff is lame stuff, we've put together a list of 10 awesome and affordable gifts for teens (5 girl gifts; 5 guy gifts).
