I think the Estonian one (“Osta euroopat”) is wrong and translates to “Buy parts of Europe”.
I’m not fluent (just Finnish) so I don’t know what the actual correct translation would be, though looking into it I believe it might have to be three words rather than two. “Osta Euroopast” might be close but would AFAIK translate to “Buy from Europe” rather than “Buy European”.

It translates to “Buy Europe”. You are correct with “Osta Euroopast” but I think “Osta Euroopalist” or “Osta Euroopalikku” might also work.
