As you might expect, there are some conditions. You'll need to purchase a new line of service for at least one of the phones, and ultimately you'll be paying full price up front for both; the free one comes in the form of a $33.33 monthly bill credit over 24 months.

What's more, you can't combine this with Verizon's "select trade-in" offers, though you can get "market value" for a trade-in. All that said, the end result here is an $800 savings -- something to consider if you're in the market for a pair of Google's new flagships.
