On several different things. Let's see...

After spending $200 on a nice supply of Frappuccino and $50 taking myself out to an awesome steak and lobster dinner at a local place, I would hire someone to clean my house. From top to bottom. $150 would be SO worth sparkling toilets and a really white shower floor that I didn't kill myself to get.

With 3 very messy kids, 2 cats, 2 kittens, a turtle and 2 hermit crabs, $100 would have to go for "cheap" area rugs. I'm not dumb enough to replace my carpet with them still living here. Ahhh to have new, soft padding under my toes. Mmm!

Did I mention a little for some really comfy flannel sheets and a couple of nice fluffy pillows?

The rest woule be for art supplies. Especially indulgent, expensive supplies. I can't help it!

Or maybe I'd scrap all that and opt to have my legs professionally de-fuzzed with a laser. I'd never have to buy a razor agaiin. Ahhhh.
