Don't want to jinx it but it seems like I was able to get the 1y family subscription even though I was already a member.
All I did was login with my account, then order the 1y subscription and then in the page to enter the CC details, I changed the email to a different one. I then got an email with the key.
All seems to work after I updated the key in the desktop app. I now says I have a 1y sub.
Just thought I would share,
