Google has added their Glass Explorer Edition to the US play Store today, negating the need for the dedicated sign-up and order page that they previously had it listed on. The selling price still remains at $1500 and is offered in a variety of colors, 5 to be exact, to make them a little more fitting to your style plus you get a free frame or shade with your purchase.
The Play Store page also has the various accessories available to purchase individually. Those include frames, 4 style options, for your prescriptions lenses ($225), Shades in 3 styles ($150) and the Stereo or Mono Earbuds ($85).
Head on into the Play Store to take a look and get an order placed if you do so desire.
