Amazon offers Prime members the View-Master Virtual Reality Starter Pack, model no. DLL68, for $20.95 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $6.52.) That's the lowest total price we could find by $4, although it was a buck less the week of Black Friday. It includes a View-Master VR viewer, preview reel, and adapter for iPhone 5, 5c, and 5s. It works with an app on your smartphone to create a 3D experience.
