I'm going to go to Finland (Kajaani) and stay for about 7 month

I really like drinking soy-milk and also not so good drinking cow milk so my family said I should take their soy-milk maker with me.
But I've heard that Finland is very cold


so As the topic : Could I find soybean in market there?
and also Is there any cheep ingredients I can use to make meals ?
Thank~
