Is this a good time to BUY a license?

Considering that I'm starting to use Norton (trial user), and I am reading all this flame war about Norton Security and chat transcripts, I'm wondering if this is a good time to BUY a license (NIS or 360, whathever is cheaper at the store), because Norton Security is probaby going to be more expensive than a deal at Amazon (NIS x 3 PCs x 1 year for 32 dollars) and more expensive than at G2A (360 x 3 PCs x 1 year for about 18 dollars, can I trust this?).
