Thanks for the info. Just to add, that link says that they'll give a $200 Visa prepaid card for any Verizon smartphone or tablet, if you click through their link - valid thru 12/5.
Forgive me for being greedy, but I'm wondering if this promotion would be eligible to stack with the VZW trade-in and activation/upgrade fee waiver promotions, since like you said the order is fulfilled by VZW. Seems reasonable, and it'd be rather sick. I just looked into this and called both Comcast and VZW:
Comcast said that those promotions DO stack, and that you don't have to be a Comcast customer. Then VZW said that the waiver and trade-in promotions DO NOT stack, and that this Comcast promotion is only for new VZW customers - current customers who want to upgrade (like me) are not eligible. I wanted to call Comcast back to confirm and get their story straight, but alas, it seems that their reps have shut down for the night.
So, some conflicting info here. If anyone has further insight on this promotion, please enlighten us.
