It's actually still possible to get the device for $200 after rebate. If you sign a 2-yr agreement through Verizon at Comcast, then they'll sell you the phone for $299 and give you a $100 Visa gift card. You don't need to be a Comcast or Xfinity customer to qualify.

If you are an Xfinity customer, you can do even better by electing to receive $10 off your Xfinity bill every month for 12 months instead of the $100 gift card. That will come out to a total of $120. So you'll effectively be buying the phone for $180.
Order being fullfilled via Verizon, so no waiting on shipping. It says 6 weeks after the order for the card, which at this rate may arrive before the phones purchased from 3rd parties.
