if i get this in store, do i have to get each one of them or do they have that already bundle?
As long as it's not an online only offer you can buy them in-store together to make sure you get the bundle discount while PMing the game down the line. Most store employees would be oblivious to the bundle issue anyways. It's the online CS reps that give me a hard time about PMing bundle offers. It was a pain trying to get an online PM for my Assassin's Creed .com preorder. They consider the DLC as the bonus item and therefore a "bundle."
In-store however, the register won't deny you a PM because it doesn't recognize bundle offers anyway. Only an alert employee would catch it if even that. The receipt will have an asteriks with "Solution Plus" denoting a bundle but again, I've yet to run across any employee that would cockblock me on that.
