Verizon is advertising the 5C, but not the 5S.
In case you haven't heard, the 5S is not available for preorder. OP is asking about the 5S, not the 5C.
Edit: It appears AT&T is also only advertising the 5C at this time. Clearly Apple and carriers are focused on the 5C much more than the 5S since the 5C will bring in more profit. In a marketing standpoint is a good thing, but overall its like they are ignoring the 5S. Why ignore your flagship product?
