The market is a place where buyers and sellers interact to purchase certain goods or services. Business competition can occur anywhere, even in the Wage Purwokerto market. This happens because sellers do not want their competitors to be superior, so some sellers who have more capital lower the prices of their goods far below market prices to prevent jealousy or resentment among other grocery sellers. This price reduction is not solely to attract more consumers. The research method used was a qualitative field approach with data collection techniques through observation, interviews, and documentation. The object of the study was a grocery store in the Wage Purwokerto market. Data sources were obtained from interviews with grocery store vendors Anyar and Tasirah, as well as from supporting documents and relevant literature. The data were analyzed using qualitative methods, including data reduction, data presentation, and concluding each analysis. The results of trade practices show that the problems between Anyar and Tasirah wholesalers at the Wage Market in Purwokerto are not only related to sales locations. The forms of competition that arise among wholesalers at the Wage Market in Purwokerto generally include price competition and customer service. This competition arises naturally due to the large number of merchants selling similar goods in the same market area. From the perspective of Islamic Business Ethics, some of the competition among merchants is in accordance with Islamic principles, such as maintaining honesty in measurement and competing fairly by increasing customer satisfaction.
