Out here in the forest of Finland, there is no real large supermarkets or even a mall nearby. But have no fear, just a short ride away is the Häijään Säästömarket.
They have not only food and beer, but also all sorts of things, kind of like a very mini Wal-mart. The prices are cheap, for Finland. Every time I come back they manage to expand in some way. A great plus for me was when they started accepting credit cards.
