My addictions are first and foremost dog sports/stuff, then probably dice. I, like @Konas, like to get new dice for each character... the problem is that I assign them a small color palette and then EVERY time I see dice that fit those colors, I want those dice for that character as well. And then it just never ends.
I also have an earring addiction. It's gotten so bad that people don't know what earrings to get me as gifts anymore.
Oh, and jackets... I have a really bad jacket problem. I may have more jackets than I do shirts. Definitely more jackets than pants or dresses.
