Primary data was collected through questionnaires that had been tested for validity and reliability.The results of the study show that E-WOM has a significant influence on the purchasing decisions of Erigo products, where the more positive the E-WOM, the higher the purchasing decision. Additionally, the Cross Selling strategy was also found to have a positive influence on purchasing decisions, with customers who received additional product offers being more likely to purchase the main product.
