For clarification, this is a 1 year (12 month) gift card subscription.
PokerGuy, yea my Pandora One sub is not up until October. However, these gift cards will stack onto your existing subscription. I confirmed this with Pandora via email, "As for Pandora One gift cards, they will continue to be honored for the foreseeable future. For example, new gift subscriptions are $24, 6-month subscriptions when purchased online, but if you happen to purchase a $36 annual subscription, or happen to have an unredeemed annual gift subscription, you will still be able to redeem it, despite us no longer offering the annual subscription. "
They also spoke about loyality pricing, "Your subscription will then continue at the $3.99/month rate uninterrupted and payment will be automatically charged in future months, unless your card information becomes out of date, or you decide to change your auto renewal settings.
If you allow your subscription to expire, you will only have access to the $4.99/month rate for new subscribers if you decide to upgrade again. "
So even at $3.99/month, $47.88 a year is still more than $36.00. Thus you will save $11.88 a year.
At $4.99/month, the savings increase to $23.88 per year.
