Yeah but consider the time-value of money. You could do so much better investing the 70 grand and paying month-to-month. That's finance 101. Even if the prices go up, you're better off holding onto your money and paying for the service as you receive it.
Seriously. Even at a measley 2% APR, a savings account would earn you $116/month (on $70,000) which would probably cover any forseeable rate hikes over the subscriber's lifetime.
