Last minute gift ideas?

So, here's the situation - my wife and I have always allotted a certain amount of money for presents for each other, family, etc. We got things done really early this year and have spent all the money allotted, I know what I'm getting, she knows what she's getting, etc.

The thing she DOESN'T know is that I've horded away a couple hundred dollars over the past few months (she watches the finances like a hawk), so I want to get her an extra something or somethings...the problem is, I didn't actually think about the what until just today (finals have just finished for me).

Any last-minute ideas? I don't have to spend all of that money, but something where the gesture will be really appreciated (I know you can't do a ton with a couple hundred bucks).

Maybe this thread will evolve into something of use for other Clutchfanners out there - I'm especially interested in like all five ladies on the board responding, as I can't ask my wife what she wants because a) she'd then know I have mystery funds, and b) honestly, I've already bought her almost everything I can think of.

Thanks in advance!

 

Check. I already have standing orders to never buy her jewelery.

The good stuff is expensive and she'd be better at picking it out than I would.
