The link gets me to Blizzard store but there is only 1, 3, and 6 months subscription. And the page mentioning 12 months made no obvious mention if it expired or was a limited time offer. The only thing I could see is the free mounts were available through mid January but not the subscription.
So I am wondering if there’s a bug with Blizzard store or if that 12 month sub page was outdated
