I'm a 1000% sure the place I order my stuff from in Germany doesn't have a representative in Finland.

That's the whole damn point of the EU.

I think there might be some regulation on having the instructions written in the native language, but that's like 100€ to a translator for an one-time job. No laptop comes with an extensive manual.

Warranty terms are EU-wide too mostly, there are some country-specific exceptions, but nothing that would require a huge legal team to handle.

Yeah that's what I thought, I've ordered from many places in the EU that do not have any kind of presence or representative in my country.
