Renew NAV for 1 PC 1 year unavailable?

On the UK site, I do not see the option for renewing my subscription to NAV for 1 PC and 1 year. The only options appear to be 3PC or 5 user pack. Since I am the only user on only 1 PC I do not want to pay for 3 or 5.

 

I have 15 days left on my current subscription. Currently running NAV 2012.

 

I use Windows XP pro SP3 all updates.

 

I can see it is available on Amazon.com (US, payment in $) but not on Amazon UK nor Norton UK. I'd rarther pay in £. plus Amazon free delivery will not work for UK address

 

Can someone point me to a link to renew for just 1 PC 1 user, based in UK please.
