The latest Dragon Age: Legends newsletter offers a promo code for a free Holiday pack, which includes a 24-hour 2x happiness perk for your castle and a package of 5 Revitalize potions. The codes are not unique, so anyone who plays Dragon Age: Legends can redeem them for some sweet in-game freebies, whether or not you're subscribed to the newsletter. You have until December 23, 2011 to redeem the code in-game for the freebies.
This Holiday Pack code can be redeemed in-game by navigating to the in-game store (the red tent icon with the $ sign). And it should work for both Google+ and Facebook versions of the game.
