http://www.chinavasion.com/bluetooth-headsets/bluetooth-wireless-mini-phone/I made a post on goods, but it didn't get much traffic since I guess I was a little vague on what I wanted to do. I'm thinking buy them up 8 at a time to save on postage, and since they can fit into first class mail when bundled up, I can resell at 2.2 BTC/unit and break even, (+.1 would be about $.50 profit) and since you can use them to take calls without getting your big ass smartphone out of it's case and talk to a brick, it might go over well, especially if you have trouble picking up calls with a touchscreen.
