I went to my local Wal-mart to find a copy of NIS 2011 to renew our trial subscription on our PC. They had a copy of NIS 2011 1-year 3 PC’s in a DVD case for $35.00. I bought it, but it felt odd, considering it was substantially cheaper than other places. So I was just wondering if this was what I needed to get or if it’s something different. Thanks!
