I bought mine in a box. DVD. From Amazon US. Prices fluctuate wildly, like the stock market. I bought Plus when the price dipped for a day to two to $50 USD. (Or maybe it was $45?) Still requires Internet for online activation. And for update.
After installation, I removed a few of the unasked for components, as some have suggested here.
I got mine couple of years back directly from their website and it came on a DVD not a CD, The box also contains an thick installation manual in like 30 languages, actual installation instructions was like 2-3 pages... LOL
