2010 Renewal Notice Confusion from within Norton's website

I've done a search and I've seen a wide range of answers to this ever nagging question.  My subscription to Internet Security 2010 expires in 12 days.  I do not have or want auto renewal so its turned off.  My account shows I initially bought the product for 3 pc's and its currently loaded on 2.

 

I went to Express to renew and it says the cost is $59.99.  Does not indicate how many pc's the renewal is for.  Deleted cart.

 

I then went to Norton's home page and followed the renew your subscription link and the cost through this link for renewal is $49.99.   It also does not show the number of pc's the renewal is for.

 

Can anyone explain the difference in pricing within Norton's website?   Also if I elect either price option how do I know that my renewal will be good again on the 2 pc's that I currently use?

 

Thank you for your response.   Jim
