My lunch at McDonald's was more than this. Thanks to a sweet $20 rebate, you can pick up this small, very nicely rated bluetooth headset for your phone for just $7.99 folks. It ships for free. And there's no tax except in CA. Rebate expires 1/15/10 but I'm pretty sure this offer will be gone waaaay before then.
