Walmart offers the GoPro Hero5 Black 4K Action Camera, model no. CHDHX-501, bundled with a $50 Walmart Gift Card for $399 with free shipping. Assuming you'll use the credit, that's the lowest total price we could find by $46, although we saw it for $6 less last week. 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.
