BGR has reported that Verizon is going to be offering a 2-for-1 special on the Droid starting on December 4th, with the requirement that you activate a new line. It’s definitely worth waiting a few days if you are considering buying multiple Droids.
Update, 12/4. More details have emerged at BGR. You can only get an HTC Droid Eris as your free phone, not a Motorola Droid.
