The sampling technique used was non-probability sampling with purposive sampling. The sample size was determined using the Lemeshow formula, resulting in 110 Ask Coffee consumers as respondents. Data were collected through observation, questionnaires, and documentation, and were analyzed using validity tests, reliability tests, classical assumption tests, multiple linear regression analysis, t-tests, F-tests, and the coefficient of determination. The results showed that Word of Mouth had a positive and significant effect on Purchase Decision, with a significance value of 0.000.
