Today only, MidnightBox offers this Xpand Universal Active Shutter 3D Glasses 2-Pack, model no. X103, for $80.95 plus $3.99 for shipping. That's $42.47 per pair and just a buck more than our mention for one pair last February. (It's also a current price low for this quantity by $34.) They're compatible with many active 3D televisions and come with extra batteries, nose pieces, and a microfiber bag.
