Think of it this way. You're paying for packs and stubs. If you have an Xbox and and a PS5 and you play the game and earn items; it shows on both platforms. But if you buy stubs during a PS sale; those stubs are only added to the PS account. So say you have 600K in stubs and you buy 150K on the PS system. That gives you 750K on the PS constantly le. But if you sing into your XBox; you'll only have the original 600.
So if pre-order bonuses are in fact 'purchases'; they won't combine.
Don't you every wonder why when they have a stub sale it's only for one platform at a time?
Now with what I just said; if you buy the DD version for the PS4 AND the Switch. When you open the packs; those cards will be tied to that console (just like if you bought stubs).
Also, think of it like how they gave out a pack with Finest Harper. You didn't get one for each console. You got one chance at that pack.
