I wish I could tell you, Tony. I know I've asked this question of another group, and that's the answer I received. I've been looking for it all morning but I don't remember where I asked it...

I'll keep looking and let you know.

I'm certain, though, that lots of people bought multiple Chromecasts, particularly in that first batch because it gave them three free months of Netflix. Many people bought multiples because you could keep putting in codes and getting free months (although it would only really work two or three times because the codes were only good through 2013).
