Wind Rider Cub Not Mailed

I bought the Wind Rider Cub from the Blizzard Store and it arrived a few hours ago. I went to www.battle.net/redeem and attached it to my account, following the instructions provided, but it was never mailed to any of my characters. I've logged out of the character, account and entire game several times over the last few hours, but nothing.

The Gryphon Hatchling I bought a month ago was mailed to my characters almost instantly. Am I doing something wrong?
