What's the one thing you will always splurge on?

I love a deal, don't get me wrong. But there are certain items that I will not budge on spending money on.

For me, it's jewelry. If I need something costume-y, that's one thing. But when it comes to earrings, everyday jewelry that I wear at all times, and gifts (for myself), I'm not going cheap. That's why I don't have a big collection, but what I have is nice!
