iPhone 7 Battery Case, Alpatronix BX180 4.7-inch 3200mAh Slim Rechargeable Extended Protective Portable Charging Case for iPhone 7 with free bluetooth speakers $29.95

This alpatronix battery case for IPhone 7 comes with two Bluetooth speakers for free. Just add them to cart and it subtracts the speakers at checkout. The promo says 1 free item but it works for both for me.
