No shopping on Sunday: You can go shopping in Germany everyday except Sunday. This opening hours law has been around for a very long time. Shops, supermarkets and even pharmacies (except the emergency pharmacies) are closed on Sunday. German people are very strict about no Sunday shopping rule. The main consideration is for workers to have at least one day to rest. So just make sure that you fulfill your needs on Saturday.
