Life goes on...
Yeah to Finland and it seems most European countries it's up to twenty euro. It's ridiculous when postage to different European countries costs different amounts. Do the postal systems in some countries actually have a sudden like that? In Finland it doesn't matter which European country you post to it will cost the same.
I think it depends on what you are using. Commercial carriers usually doen't have flat rate but based on their costs. So that would mean cheaper for closer countries.
In Latvia postal service is at flat rate for up to 2kg. Above that it varies on country by country bases even in EU.
