custom macbook not available in branch+ tax free

Hello guys,

i am planning to buy a macbook pro from apple store in Barcelona- Spain.

so i want to customize my macbook pro specially for the Keyboard to be US instead of spanish layout.

So I found that the branch do not have macbook pro in the branch with US layout ( checked online)

so i have to buy it online to get it ready for pick up when I visit the branch.

but i saw that i won’t get TAX-free if i bought it online and I will only get it if i bought offilne from the store (paid in the store)

so I don’t know how to get a US keyboard layout or order it to be ready specially that am not staying a lot in spain, it’s just 4 days
