In case anyone is looking to go to their local Radio Shack to take advantage of this deal. First, the employee I dealt with insisted the $100 off was only for new Verizon customers. Second, they didn't let me renew "early", even though I could have done so through their web site (I'm only a few days from my renewal).
The employee insisted that the $100 off was only for new customers, I was tempted to order the phone right there on my phone just to show him that the web site was giving me the offer.
The other problem I found in trying to order online is that the web site seemed to insist on changing my plan and wasn't honoring the fact that I can be grandfathered into my existing plan. That's why even though it may be cheaper to get the phone elsewhere I'm inclined to get it at my Verizon store.
