As one of its daily deals, A4C offers the used Samsung Gear VR Headset for $19.95 with free shipping. That's $20 under the lowest price we could find for it new and the best price we've seen in any condition. This 2016 model features 360° virtual reality viewing, a new external touchpad, USB Type-C, and 101° field of view (previous models had a 96° field of view). Deal ends today.
