Evaluation of the Quality of Second-Hand Clothes Trading Websites using the VIKOR and MOORA Methods

Along with technology, people’s living standards have also improved in the same direction. Long-distance shopping trips are no longer preferred by people. Many consumers now find it more appealing to shop while sitting at home and avoiding the crowds while also finding what they are looking for more quickly. However, this impressive opportunity provided by technology can sometimes create difficulties for customers. In the online realm, there are various alternative e-commerce websites. This led to frequent consideration of the query, "Which website is better for me to shop from?". Here convenience means price, security, product variety, etc. such criteria. This rightful consideration of consumers has led many researchers to enter this field and have enabled them to use decision-making methods during the selection of e-commerce sites. From the 2000s to the present, second-hand goods have gained popularity again. The fact that second-hand goods are generally cheaper than new ones encourages thrifty consumers to buy second-hand goods because of their price advantages. In addition, many consumers may turn to second-hand sources because they are concerned about the scarcity of natural resources and the volume of waste generated. The trend toward buying second-hand products is driven by the issue of sustainability, which has recently received significant attention. In this study, the quality of three e-commerce sites selling second-hand clothes in Turkey was evaluated using various multi-criteria decision-making methods. The criteria taken into consideration while shopping on the e-commerce sites in question were determined from studies in the literature and from a website called "Şikayetvar" that is frequently visited by internet users. The weights of the determined criteria were then calculated using the AHP method. The sites were then compared using the VIKOR and MOORA methods.
