Upgrade from Internet Security to Safe without losing money?

Hi,

I want to protect my Android devices with SAFE but I already have Internet Security paid for and running on three computers. Adding Mobile Security for three mobile devices means I would be paying more than I would be paying for SAFE for five devices. So, I would prefer to buy SAFE as a total solution for all my hardware.

The problem is that I am only about halfway through my Internet Security subscription period. When trying to buy SAFE I can see no mention of how I could avoid paying a double price, i.e. the remaining subscription period for Internet Security AND the beginning of the subscription period for SAFE since the two would overlap for about half a year.

Is there a way out of this situation or will I be forced to pay more than seems fair to me?

Thank you,

MOT
