What's your favourite thing to mindlessly blow your money on? I've noticed recently I've been buying a lot of CD's, I love them. I don't have enough time for books, or DVD's or anything like that, but with music I can do stuff (such as study or drive) while using them. And I don't get the same satisfaction buying an album of iTunes as I do physically owning the CD.

So yeah. What's your favourite thing to buy?
