Paring Down

In preparation for moving, I'm trying to get rid of a few things. But for the life of me, I can't figure out what I'm supposed to do with cosmetics I don't want anymore - body sprays I've had forever, excessive amounts of Purell, extra hair spray bottles, Nair... I just keep carting them around from house to house, but seriously, I'm NEVER going to use these things.

Also, since I hardly ever wear makeup, any type of makeup lasts me forever. But this article says that basically I should throw it all away.

I need help!
