Needs clearer directions for current Premium subscribers!
So I purchased this so I could renew my subscription for another year. The caveat is, you can't renew until your current sub is up.  I had to wait until it ran out, then the card worked. I didn't realize this when I bought it because there's no signage on it saying it isn't for add-on renewals, it seems it's only for non-premium (or premium lapsed)/new accounts going to premium.
