For an individual player who doesn't associate with the online community other than the game itself, they won't actually know there's been any extreme sale on Call Off Duty if they had already owned the skin. Same would apply to the ownership of the class. That's a likely reason that the deals have not been largely announced.

Oh, and there's also a bundle deal selling off four of the seven Christmas skins. It's a sale, but should you have purchased them last year when they were 20 Gas, you still got a better deal.
