Christmas Gift Ideas for Kids

I'm trying to figure out why my kids' mp3 headphones seem to go extinct in this house so quickly.  Cat chews up one pair, another pair stops working, can't find one set, left one set at somebody's house - ack!  I need a great sale to find out where are ipod nano headphones on sale. I also like skimming the clearance racks in stores so I can stuff their stockings at the holidays with them.  Yes, I am already thinking about Christmas.  With school starting next week, Christmas will come riding up sooner rather than later!
