Bundle more expensive?

[Nachtrae]

I was looking into purchasing the game and the dlc for a friend as a gift, but I noticed something odd when I looked at the price of the bundle. Namely, buying the bundle at 66% discount is more expensive than buying the two seperate at least if you use euros.

Price of individual games: 6,23€
Bundle cost: 6,45€

I know it's just 22 cents, but it just stood out to me.
