As one of its daily deals, A4C offers the refurbished Samsung Gear VR Headset in Frost White, model no. SM-R322NZWAXAR, for $49.95 with free shipping. That's tied with our refurb mention from three weeks ago as the best price we've seen for this headset in any condition. (It's also $21 under the lowest price we could find for a new one today.) It features 360° virtual reality viewing via Oculus-driven software. Deal ends today.
Note: A 90-day A4C warranty applies.
