Since you are buying it through Best Buy - you won't get the "New Every 2" deal. If you were able to secure the phone through a Verizon store you could get $50 off at best, so a new 2 year contract on this phone would cost you $150 vs $200 (Technically $250 less the $100 Verizon debit card you get back).
My NE2 is $100 but my upgrade isn't until Aug 11th. Haven't had any luck getting it pushed up since my phone died. So the X would be $99.99 if your NE2 is $100. I also heard some BB stores will take a refund on the gift card if you want to go to the VZW store.
