Happy to see that even the Norton anti-virus homepage totally acknowledges that their prices get crazy expensive if you let the subscription renew. Next step: how about don’t do that scammy behaviour in the first place.

Most people are probably fine without specific antivirus software now Windows comes with one built in. But if you do feel you need one, then never a license renew before seeing if buying as a new customer is far better value. With Norton, it absolutely is, and it’s far fro alone.
