Here in Skagen every thursday you can go to the salvation army and fill a big sack with clothes for 100 kroner (15$). Since Skagen is the place to relax for the rich and famous they drop of their used clothes there and you can often find Buberry coats, Chanel dresses etc etc.
I have never been there cause I don't care for designer clothes, but I like the idea of a bum running around in a real expensive coat
