GeekBuying offers the Xiaomi Yi WiFi 1080p Action Camera in White bundled with a Kingma Waterproof Case for $79.99 with free shipping. That's tied with our expired mention from two days ago and $23 under the lowest total price we could find for these items sold separately elsewhere. The camera features 1080p video capture, up to 60fps recording, a Sony Exmor R 16-megapixel CMOS sensor, WiFi, Bluetooth, 155° wide-angle lens, and water resistance up to 130 feet (without the Kingma case).
Don't want the case? You can also get the Xiaomi Yi WiFi 1080p Action Camera alone for $68.88 with free shipping. That's tied with our expired mention from two days ago and the lowest total price we've seen for this camera. (It's a current low by $18.)
