As the title says, Paradox's own webshop is currently having a sale on Victoria games and DLC (though they don't seem to sell the sprite packs). I think this is notable because the Steam version of A House Divided only rarely goes on sale.
Here's the link to the store: http://www.paradoxplaza.com/shop

Victoria II
Victoria II: A House Divided
