Synchronise AVG programs/services

I have AVG AntiVirus for 3comp, 2yrs,. PC Tuneup 1 comp, 2yrs,.    Safe surf 1comp, 2yrs (have'nt used this yet!!).  I use 2 comps; Win7, Win8.  All AVG pgms have different renewal dates.

What will it cost to synchronise the renewal dates, and allow me to use Tuneup on two or three computers as well?    
I dont think SafeSurf is being used, so probably dont need it.

About Zen? Is it only for premium versions, Your info is unclear?? 
Thanks  Howard.
