Bests & Worsts Reviews from Amazon

I was looking for an extension of the subscription on my BD Total Security software and found this on Amazon at even steeper disocunt ($30.99 for 2 yr extension). Instruction in email show how to install on existing software package - in BitDefender Central account login, click on My Subscription, select activate code, copy code (Product Key) from Amazon email into box provided on site and select Extend Subscription if that applies. Works like a charm and I extended my subscription with ease after email from Amazon was received.
