This study explores the motivations and barriers influencing consumer decisions to purchase second-hand products across three key categories: fashion (sweaters, jeans, and shoes), furniture (dinner tables, armchairs, and bookcases), and electronics (smartphones, microwaves, and washing machines). While prior research has examined second-hand consumption broadly, this study identifies significant variations in consumer attitudes across product types. Using survey data from 864 participants, we analyse 18 motivations and barriers using ANOVA. Findings reveal that motivations such as economy and sustainability are prominent across all categories, while barriers vary by product type. Hygiene concerns are particularly relevant for shoes and microwaves, while issues of cluttered shopping environments primarily deter fashion purchases. Second-hand furniture emerges as the most positively perceived category, whereas electronics face the greatest scepticism due to concerns about obsolescence and warranties. This underscores the need for product-specific strategies in second-hand markets, informing policymakers, retailers, and designers seeking to promote sustainable consumption.
