Walmart offers the GoPro Hero5 Black 4K Action Camera for $319.99 with free shipping. That's the lowest price we could find by $79, although we saw it bundled with a 32GB MicroSD card for $20 less last month. This 4-oz. camera is waterproof up to 33 feet without a housing and features a 2" color touchscreen LCD, up to 4K video recording at 30fps, 12-megapixel photo resolution, voice control, three microphones, WiFi, Bluetooth, micro-HDMI, microSD slot, and rechargeable Li-ion battery.
