A4C offers the refurbished MoGo Talk XD Bluetooth Headset & Case System for iPhone 4 for $6.95 with free shipping. That's $6 under the lowest total price we could find for a new one. It folds flat so that you can store it in the iPhone 4 case and is compatible with iPhone voice control. Deal ends June 13.

A 90-day A4C warranty applies.
