Worked fine and is a good deal vs paying directly for a year.
I purchased 2 cards and waited to post this because I wanted to verify that I could add both to my account.  I added the second card last month and had no issues.  I read in other reviews that people could not add the cards to their account. I waited until my current subscription expired and added the first card with no issues.  Then after 3 months I was able to add the second.  So now I've managed to save some money for 2 years of annual subscription.<br />Good deal.
