If I purchase Norton 360 from another vendor can I add it to my current subscription?

[Edit: Clarified subject]

You can as long as you purchase the same 360 version as you currently use. Be sure you have turned off the Automatic Renewal for your current subscription if you want to do this.

You have 2 options.

  • One is to wait until you have only one or two days remaining on the old subscription before entering the the new product key as you will lose any remaining time on the old subscription. 
  • Two is to contact Norton Support and ask them to add the new subscription time to your existing subscription.    www.norton.com/contactcs
