Nop eShop only.
No luck for me then, tried purchasing it. eShop won't accept my credit card, tried it 3x and all failed but I got charged, just called my bank and they said that they will drop the charges if nintendo will not confirm that the transaction got through within 15days.
Anyways, will look on our local game stores if they sell eShop funds (is that a thing? Like steam cash or something?).
