No, I am not talking about the Norton Security license that I have used on my computer which has a 365-days expiry.
I am talking about the retail box that I buy at retail stores. If I buy three retail Norton Security box (5-device) now, can I used the licenses from the three retail Norton Security box for the next 3 years, ie. first box for 2016, second box for 2017, third box for 2018?
Is the above ok or must I use all three boxes within 2016?
