Dire Dark Warsmith Weapon bundle price?

So I recently bought the Dire Dark Warsmith weapon pack, which had the Pistol, Blunderbuss, Cutlass and eye of reach. But now the bundle has been updated to unclude the four remaining weapons. Throwing Knives, Double Pistol and Harpoon gun. For the same price of 999 with no discount for having half the bundle already. So now cause I bought the pack earlier, it's way more exspensive to buy the remaining weapon for the sets? This dosn't feel right.
