Dancing-Hot via eBay offers this DIY Cardboard Virtual Reality Toolkit for $1.99 with free shipping. That's tied with our mention from two weeks ago and the lowest total price we've seen for such a kit. (It's also a current low by $4.) Like the Google Cardboard, this kit includes everything you need to turn your smartphone into a VR headset: pre-cut cardboard, lenses, a magnet, Velcro, and rubberband.
