Got $10 burning a hole in your pocket, but don't know what to spend it on? No problem. Just visit SomethingStore, place an order, and within 7 days the company will ship something to your door. You won't know what it is, and you may hate it. But hey, shipping is free.

The concept reminds us a lot of the random bag of crap that often concludes Woot-Offs. For some reason, that random bag of goodies is one of the most popular items you can buy, even if you don't know what's in it.

If you'd rather know exactly what you're getting for your money, make sure to check out Wants for Sale tomorrow. Artists Justin Gignac and Christine Santora use the site to sell paintings of things they want - for the price of the actual items. Buy a picture of a piece of pizza or a Nintendo Wii and Gignac and Santora will use the money to buy the item. They'll have a fresh batch of paintings available Friday. And this time they're going with a theme - Vegas. You'll be able to help them fund a trip to Vegas by purchasing art.

Or you could just save your money for retirement, your kids' college fund, or to buy things you actually want for yourself. But what's the fun in that?
