Verizon Wireless offers the LG Cam Shooting Grip for LG G5 for $9.99 with free shipping. (AT&T offers it for the same price.) That's tied with our July mention and the lowest price we could find by $2. It gives you more stability when taking photos and has a built-in 1,200-mAh battery.

Update: The price has increased at Verizon Wireless; however, AT&T still offers it for the same price.
