Powerbook spanish keyboard in Apple Store?

[Mahler]

I'm buying a powerbook in december, since I'm a native spanish speaker I would like the keyboard to be in spanish.

When you order it from the online store you can custom order it with this keyboard (and it's completely free!!). But I will have an Apple store very near to where i'll be staying in the US (Chicago, IL), so I was wondering, if I buy the PB at the physical apple Store (instant gratification!!!) can they change the keyboard there for free? Or do they have systems already configured like that there?

Thanks!
