Just an update one year later as I received notice my savings was falling off - my ISP confirmed they would not be offering any discounts in the 2nd year as Billshark claimed would be applied at this time and were expecting me to pay for savings upfront. I was also signed up for a service that was waived in order to get the savings that would be falling off, so overall would have had to pay more. Definitely avoid the Billshark service.
