This study aims to analyze the effect of product arrangement on consumer purchasing decisions at Alfamidi Jl. Tuasan, Medan. Product arrangement is a crucial visual merchandising strategy in the modern retail industry to attract consumer attention and increase sales. The study used a quantitative approach with an associative method, involving 30 respondents selected through accidental sampling techniques. Data were collected using a questionnaire with a 5-point Likert scale and analyzed using simple linear regression with the help of SPSS version 25. The results showed that product arrangement had a positive and significant effect on consumer purchasing decisions with a coefficient of determination (R²) of 90.2%. The regression equation Y = 1.245 + 0.675X shows that every one unit increase in product arrangement will increase purchasing decisions by 0.675 units. The t-test produced a calculated t value of 16.071> t table 2.048 with a significance of 0.000 <0.05, confirming the research hypothesis. This finding confirms that product layout elements such as ease of access, visual appeal, and layout comfort play a vital role in influencing consumer behavior and increasing the effectiveness of retail marketing strategies.
