SUPERFLEX started the Free Shop project in Bremen in 2003. Since then, Free Shops have been realised in Japan, Mexico, Poland, Denmark, Norway and the USA. It can in principle be carried out in any shop (from a greengrocer’s through to a pharmacy or a snack bar). When they go to the cash desk, customers are given a receipt totalling 0, i.e. they don’t have to pay for their purchases. There are no signs in the shops themselves announcing that goods or services are “free of charge”; only when you come to pay does it become clear that this is no ordinary purchase and that the conventional logic of purchase – goods for money – has been turned on its head.
