I keep getting tempted to buy a prize candle. They come with various names, like Ring Candle, Diamond Candle, etc. Basically, it's Cracker Jack for adult females who really, really like candles. You burn the candle, get to a foil packet, and if you're lucky it has a decent fragrance and there's a cheap $10 ring that isn't too ugly that you might not feel too ashamed to give to a neighbor's kid.
The only way I keep talking myself out of it is by promising myself that I will get a Yankee Candle and throw a piece of my own jewelry in it, and then pretend to be surprised.
