Online shopping phenomena are governed by a number of consumer acceptance and behaviour characteristics and grounded in theoretical aspects of consumer decision making. There are a number of factors that affect what we buy, when we buy, and why we buy. In reference to buying online, the factors that influence consumers are marketing efforts, socio-cultural influences, psychological factors, personal questions, post-decision behaviour, and experience. These factors will be further discussed by way of a consumer decision-making model for online shoppers.
