said by Zero:Keep in mind that you can only view your local pricing and not other areas of the FIOS footprint (for example in the NYC area the HD STB is $6.99). I am not saying you are incorrect just pointing out the OP is from CA and your pricing is from PA.
The price isn't going up. I just checked both existing and new customer pricing and it's still the same. You where probably looking at the cost of the Digital Adapter instead which is right above CableCARD.
