As one of its daily deals, A4C offers the used Samsung Gear VR Headset for $19 with free shipping. That's $11 under the lowest price we could find for a new unit, although we saw it for $5 less in May. (It's also a buck less than the cheapest refurb we could find elsewhere.) It features 360° virtual reality viewing via Oculus-driven software. Deal ends today.
