Through 9/30, Buy.com has the Symantec Norton Antivirus 2008 software for $25.57 after a $10 mail-in rebate. If you already have a stand-alone, retail version of any Norton or Symantec software, you can also use this $20 upgrade rebate lowering the price to $5.57 (you'll have to send in some proof of ownership: the software disc, the first page of the manual, etc., along with the receipt and UPC of this newer copy). Norton is the gold standard in Antivirus software. Shipping is free and there is no sales tax (except CA, MA, MD, TN).
