Well, that's when you consider the price of buying what you want separately. The Darksiders Franchise Pack cost me $13.50 for Darksiders 2 and all its DLC... I certainly wasn't bemoaning the loss of an extra copy of the first game. Dawn of War Franchise Pack is a similarly amazing deal at $10.
I do think it's odd that they don't give you giftable copies of EVERYTHING, but it might actually be part of the reason they're able to give you such insane discounts on bundles.
