We always buy them one huge gift and a lot of filler. Last year, we got the boys computers. We will also take them shopping for clothes a few weeks b4 xmas and let them pick out all of their clothes. I do not pick out clothes for them anymore (teenagers). We wrap all of their clothes they pick out. We also give them both 50-100 dollars a piece depending on their grades. Other things may be a cheap mp3 player, anything w/their favorite sports team, etc. This year will be a bit tougher though, my oldest is a senior in H.S. and anyone who has had one, knows how expensive that is.
