1. Changes in consumer behavior during the Covid-19 pandemic are reflected in purchasing decisions. In general, with this pandemic situation, consumers will be motivated to be careful in considering each stage of the decision because of the health risks associated with the transmission of Covid-19 and the situation of social restrictions. Changes in behavior can be seen in three perspectives of decision making, namely Rational, Experiential and Behavioral. In this perspective, consumers make rational purchasing decisions by emphasizing functional and economic aspects. Most commonly, consumers will choose the brand that offers the best price, features and services. In a pandemic situation, consumers no longer consider rationality, especially for goods that are the main needs related to health protection. Items such as masks, hand sanitizers and disinfectant liquids will be purchased regardless of the brand and at any price. Purchasing decisions are based on the availability and ease of obtaining goods.
