Here's an interesting business model, via Gizmodo: You set up a website and ask customers to pay $10. In return you send them something randomly selected from your inventory that includes new and used items ranging from kitchen knives to chocolates to designer jeans. And hey, shipping's free.

It's obviously not a traditional retail operation, but the SomethingStore has turned this idea into a slick little business. Recent "somethings" they've sent out, according to their site, include an hour glass, a RC Speed Card, a Norelco Shaver, and a Nautica Sweater. Don't get too excited though, the fun is tame; alcohol, weapons, wholesale currency, "prostitution services," and cable descramblers are among the items they don't ship.

Sure the idea is cute, but are these guys making any money? Seems like it. According to their website, they sold 1,000 somethings in the first month of operations. Considering that these guys probably get their inventory from a combination of Goodwill and the trash, and that overhead and costs are low, that's not a bad living.
