Galaxy Note 3 Spare Battery Charging System
I've been checking every single day (morning, afternoon, and night). This was the first time that I added to cart and it actually showed up. Got my 2, so I'm happy. Too bad the wireless charging covers and other accessories I was eyeing were all out of stock. Coupon came in very handy and just added an extra 2A charger, to get the free shipping.
