Staples usually has a good sale/rebate by the time I have to renew but I haven't seen it yet this year so I went searching. You can download it from the link below for just $14. You'll be sent a download link and product code by e-mail and you're good to go. (The download is from Norton, it's legit ... I just did it.) If you feel better having the product in hand you can get the disk for $18.
