Bringing this up with one of my previous replies that describes my method the best way:
As far as I saw around the web for the past few years, this is absolutely the best possible offer considering ESET's NOD32 & Smart Security app keys.
* As first, you're NOT getting only one key but the method how to get fresh key anytime you need one.
* As second, it is silly cheap compared to the actual price (not to mention renewing license every year...)
* As third, there are 3 vouches so you can be sure it works.
Offer available.
