HTC 10 will be $150 off for a limited time

Alternatively,Verizon has $200 off Androids for select users . use code "200and". You can also trade in a g4 for $300.
 
Wow so it's normally 649 which drops it down to 499 correct?

Wrong. The "normal" price is $699 but HTC has been offering $100 off for some time now. The limited time offer gives you an additional $50 off, so the price should be $549.
