Gekauft ist gekauft, bought is bought. The consumer advice center in Hamburg uses the phrase for a basic rule of German shopping. A customer who buys something in a store has no legal right to bring it back because she no longer likes it. Einzelhändler sind beim Kauf in einem Ladengeschäft nicht verpflichtet, Waren zurückzunehmen. Retailers are not obliged to take back goods bought in a store. Many shops take goods back anyway. This is called Kulanz, goodwill, and the shop sets the conditions. It may give a voucher instead of cash, for example. Defective goods are a different matter. For purchases made online, the law gives the buyer 14 days to withdraw.
