Aww, Cadence and Shining Armor do care! For those of you that didn't make it to Comic Con, Shout Factory was giving out paper tiaras for anyone that asked. They have since been popping up all over Ebay. If you need one for your pony collection, they have started giving them out with purchases of the DVD over on their website.
And if you want a greeting card from the two ponies above, head on over to this page or text ROYAL to 95323 and toss your name into the pile. Or your E-name, I like my E-name.
