I added VET TV using the App Store for my iPhone. It is charging 69.99 dollars a year,but checking online it is available for 54.99 A year. Is there a reason for the difference from one area to the other? If I would have known that, I would have signed up through online. With tax, it cost me 75 dollars, which is a lot more that 55 dollars a year. Thank you for your time and help.
